| NCP7662 Inductorless Voltage Converter The NCP7662 is a pin-compatible upgrade to the industry standard TC7660 charge pump voltage converter. It converts a +1.5 V to +15 V input to a corresponding -1.5 to -15 V output using only two low-cost capacitors, eliminating inductors and their associated cost, size and EMI. The on-board oscillator operates at a nominal frequency of 10 kHz. Frequency is increased to 35 kHz when pin 1 is connected to V+, allowing the use of smaller external capacitors. Operation below 10 kHz (for lower supply current applications) is also possible by connecting an external capacitor from OSC to ground (with pin 1 open). The NCP7662 is available in both 8-pin DIP and 8-pin small outline (SO) packages in commercial and extended temperature ranges.

In the test circuit, there is no external capacitor applied to pin 7. However, when the device is plugged into a test socket, there is usually a very small but finite stray capacitance present, of the order of 5 pF. 4. The NCP7662 can operate without an external diode over the full temperature and voltage range. This device will function in existing designs which incorporate an external diode with no degradation in overall circuit performance. http://onsemi.com 3 NCP7662 DETAILED DESCRIPTION The NCP7662 contains all the necessary circuitry to complete a negative voltage converter, with the exception of two external capacitors which may be inexpensive 1 F polarized electrolytic types. The mode of operation of the device may be best understood by considering Figure 2, which shows an idealized negative voltage converter. Capacitor C1 is charged to a voltage V+ for the half cycle when switches S1 and S3 are closed. (Note: Switches S2 and S4 are open during this half cycle.) During the second half cycle of operation, switches S2 and S4 are closed, with S1 and S3 open, thereby shifting capacitor C1 negatively by V+ volts. Charge is then transferred from C1 to C2 such that the voltage on C2 is exactly V+, assuming ideal switches and no load on C2. The NCP7662 approaches this ideal situation more closely than existing non-mechanical circuits. In the NCP7662 the four switches of Figure 2 are MOS power switches; S1 is a P-channel device and S2, S3 and S4 are N-channel devices. The main difficulty with this approach is that in integrating the switches, the substrates of S3 and S4 must always remain reverse biased with respect to their sources, but not so much as to degrade their "ON'' resistances. In addition, at circuit start up, and under output short circuit conditions (VOUT = V+), the output voltage must be sensed and the substrate bias adjusted accordingly. Failure to accomplish this would result in high power losses and probable device latchup. The problem is eliminated in the NCP7662 by a logic network which senses the output voltage (VOUT) together with the level translators, and switches the substrates of S3 and S4 to the correct level to maintain necessary reverse bias. The voltage regulator portion of the NCP7662 is an integral part of the anti-latchup circuitry; however, its inherent voltage drop can degrade operation at low voltages. Therefore, to improve low voltage operation, the "LV'' pin should be connected to GND, disabling the regulator. For supply voltages greater than 3.5 volts, the LV terminal must be left open to insure latchup proof operation and prevent device damage. V+ NCP7662 1 2 8 7 6 5 THEORETICAL POWER EFFICIENCY CONSIDERATIONS In theory, a voltage converter can approach 100% efficiency if certain conditions are met: A. The drive circuitry consumes minimal power. B. The output switches have extremely low ON resistance and virtually no offset. C. The impedances of the pump and reservoir capacitors are negligible at the pump frequency. The NCP7662 approaches these conditions for negative voltage conversion if large values of C1 and C2 are used. Energy is lost only in the transfer of charge between capacitors if a change in voltage occurs. The energy lost is defined by: E = 1/2 C1 (V12 - V22) where V1 and V2 are the voltages on C1 during the pump and transfer cycles. If the impedances of C1 and C2 are relatively high at the pump frequency (refer to Figure 2) compared to the value of RL, there will be a substantial difference in voltages V1 and V2. Therefore, it is desirable not only to make C2 as large as possible to eliminate output voltage ripple, but also to employ a correspondingly large value for C1 in order to achieve maximum efficiency of operation. Dos and Don'ts 1. Do not exceed maximum supply voltages. 2. Do not connect the LV terminal to GND for supply voltages greater than 3.5 volts. 3. Do not short circuit the output to V+ supply for voltages above 5.5 volts for extended periods; however, transient conditions including start-up are okay. 4. When using polarized capacitors in the inverting mode, the + terminal of C1 must be connected to pin 2 of the NCP7662 and the - terminal of C2 must be connected to GND. 5. If the voltage supply driving the NCP7662 has a large source impedance (25-30 ohms), then a 2.2 F capacitor from pin 8 to ground may be required to limit the rate of rise of the input voltage to less than 2 V/s.

Idealized Negative Voltage Capacitor http://onsemi.com 4 NCP7662 TYPICAL APPLICATIONS Simple Negative Voltage Converter R O The majority of applications will undoubtedly utilize the NCP7662 for generation of negative supply voltages. Figure 3 shows typical connections to provide a negative supply where a positive supply of +1.5 V to +15 V is available. Keep in mind that pin 6 (LV) is tied to the supply negative (GND) for supply voltages below 3.5 volts.

Typical electrolytic capacitors may have ESRs as high as 10 . Output Ripple RO VOUT = -V+ - V+ + (b) VOUT 10 F (a) - + Figure 3. Simple Negative Converter and its Output Equivalent The output characteristics of the circuit in Figure 3 can be approximated by an ideal voltage source in series with a resistance as shown in Figure 3b. The voltage source has a value of -(V+). The output impedance (RO) is a function of the ON resistance of the internal MOS switches (shown in Figure 2), the switching frequency, the value of C1 and C2, and the ESR (equivalent series resistance) of C1 and C2. A good first order approximation for RO is: R O ESR also affects the ripple voltage seen at the output. The total ripple is determined by 2 voltages, A and B, as shown in Figure 4. Segment A is the voltage drop across the ESR of C2 at the instant it goes from being charged by C1 (current flowing into C2) to being discharged through the load (current flowing out of C2). The magnitude of this current change is 2 IOUT, hence the total drop is 2 IOUT ESRC2 volts. Segment B is the voltage change across C2 during time t2, the half of the cycle when C2 supplies current to the load. The drop at B is IOUT t2/C2 volts. The peak-to-peak ripple voltage is the sum of these voltage drops: V RIPPLE ^ 1 2 f PUMP t2 C2 ) ESRC2 I OUT ^ 2(RSW1 ) RSW3 ) ESRC1) ) 2(RSW2 ) RSW4 ) ESRC1) ) f 1 C ) ESRC2 PUMP 1 f OSC , R SWX 2 t1 (f + PUMP R O + MOSFET switch resistance) 1 C1 0 V -(V+) B Combining the four RSWX terms as RSW, we see that: ^2 R ) SW f ) ESRC2 PUMP )4 A ESR C1 Figure 4. Output Ripple Paralleling Devices RSW, the total switch resistance, is a function of supply voltage and temperature (see the Output Source Resistance graphs), typically 23 at +25C and 5 V. Careful selection of C1 and C2 will reduce the remaining terms, minimizing the output impedance. High value capacitors will reduce the 1/(fPUMP C1) component, and low ESR capacitors will lower the ESR term. Increasing the oscillator frequency will reduce the 1/(fPUMP C1) term, but may have the side effect of a net increase in output impedance when C1 10 F and there is not enough time to fully charge the capacitors every cycle. In a typical application when fOSC = 10 kHz and C = C1 = C2 = 10 F: Any number of NCP7662 voltage converters may be paralleled to reduce output resistance (Figure 5). The reservoir capacitor, C2, serves all devices, while each device requires its own pump capacitor, C1. The resultant output resistance would be approximately: R OUT OUT + n (number of devices) R (of NCP7662) u http://onsemi.com 5 NCP7662 V+ 2 1 8 C1 + - NCP7662 7 6 5 1 2 8 7 6 5 3 4 C1 + - RL 3 4 C2 + shown in Figure 7. In order to prevent device latchup, a 1 k resistor must be used in series with the clock output. In a situation where the designer has generated the external clock frequency using TTL logic, the addition of a 10 k pullup resistor to V+ supply is required. Note that the pump frequency with external clocking, as with internal clocking, will be 1/2 of the clock frequency. Output transitions occur on the positive-going edge of the clock.

However, due to the finite efficiency of each device, the practical limit is 10 devices for light loads. The output voltage is defined by: V OUT + Figure 7.

This reduces the switching losses, and is shown in Figure 8. However, lowering the oscillator frequency will cause an undesirable increase in the impedance of the pump (C1) and reservoir (C2) capacitors; this is overcome by increasing the values of C1 and C2 by the same factor that the frequency has been reduced. For example, the addition of a 100 pF capacitor between pin 7 (Osc) and V+ will lower the oscillator frequency to 1 kHz from its nominal frequency of 10 kHz (multiple of 10), and thereby necessitate a corresponding increase in the value of C1 and C2 (from 10 F to 100 F).

Cascading Devices for Increased Output Voltage + C1 3 4 + C2 VOUT Changing the NCP7662 Oscillator Frequency It may be desirable in some applications (due to noise or other considerations) to increase the oscillator frequency. This is achieved by one of several methods described below: By connecting the Boost Pin (Pin 1) to V+, the oscillator charge and discharge current is increased and, hence the oscillator frequency is increased by approximately 3-1/2 times. The result is a decrease in the output impedance and ripple. This is of major importance for surface mount applications where capacitor size and cost are critical. Smaller capacitors, e.g., 0.1 F, can be used in conjunction with the Boost Pin in order to achieve similar output currents compared to the device free running with C1 = C2 = 1 F or 10 F. (Refer to graph of Output Source Resistance as a Function of Oscillator Frequency). Increasing the oscillator frequency can also be achieved by overdriving the oscillator from an external clock as Figure 8. Lowering Oscillator Frequency Positive Voltage Doubling The NCP7662 may be employed to achieve positive voltage doubling using the circuit shown in Figure 9. In this application, the pump inverter switches of the NCP7662 are used to charge C1 to a voltage level of V+ - VF (where V+ is the supply voltage and VF is the forward voltage on C1 plus the supply voltage (V+) applied through diode D2 to capacitor C2). The voltage thus created on C2 becomes (2 V+) - (2 VF), or twice the supply voltage minus the combined forward voltage drops of diodes D1 and D2. The source impedance of the output (VOUT) will depend on the output current, but for V+ = 5 V and an output current of 10 mA, it will be approximately 60 . http://onsemi.com 6 NCP7662 V+ NCP7662 1 2 3 4 8 7 6 5 D1 + D2 + VOUT = (2 V+) - (2 VF) can be drawn from the device. By using this circuit, and then the circuit of Figure 6, +15 V can be converted (via +7.5 V and -7.5 V) to a nominal -15 V, though with rather high series resistance (X250 ).

Positive Voltage Multiplier VOUT = (V+) - (V-) 2 R L2 Combined Negative Voltage Conversion and Positive Supply Multiplication Figure 10 combines the functions shown in Figures 3 and 9 to provide negative voltage conversion and positive voltage doubling simultaneously. This approach would be, for example, suitable for generating +9 V and -5 V from an existing +5 V supply. In this instance, capacitors C1 and C3 perform the pump and reservoir functions, respectively, for the generation of the negative voltage, while capacitors C2 and C4 are pump and reservoir, respectively, for the doubled positive voltage. There is a penalty in this configuration which combines both functions, however, in that the source impedances of the generated supplies will be somewhat higher due to the finite impedance of the common charge pump driver at pin 2 of the device.

Splitting a Supply in Half Regulated Negative Voltage Supply VOUT = -(V+) - (VF) C3 D1 D2 + + C1 4 + C2 VOUT = (2 V+) - (2 VF) + C4 In some cases, the output impedance of the NCP7662 can be a problem, particularly if the load current varies substantially. The circuit of Figure 12 can be used to overcome this by controlling the input voltage, via the MC33201 op amp, in such a way as to maintain a nearly constant output voltage. Direct feedback is advisable, since the NCP7662's output does not respond instantaneously to change in input, but only after the switching delay. The circuit shown supplies enough delay to accommodate the NCP7662, while maintaining adequate feedback. An increase in pump and storage capacitors is desirable, and the values shown provide an output impedance of less than 5 to a load of 10 mA. +8 V 56 k 50 k +8 V - + 100 k 100 1 8 7 6 5 50 k + - 10 F Figure 10.
