DESCRIPTION
The CAT660 is a charge-pump voltage converter. It will invert a 1.5V to 5.5V input to a -1.5V to -5.5V output. Only two external capacitors are needed. With a guaranteed 100mA output current capability, the CAT660 can replace a switching regulator and its inductor. Lower EMI is achieved due to the absence of an inductor. In addition, the CAT660 can double a voltage supplied from a battery or power supply. Inputs from 2.5V to 5.5V will yield a doubled, 5V to 11V output voltage. A Frequency Control pin (BOOST/FC) is provided to select either a high (80kHz) or low (10kHz) internal oscillator frequency, thus allowing quiescent current vs. capacitor size trade-offs to be made. The 80kHz frequency is selected when the FC pin is connected to V+. The operating frequency can also be adjusted with an external capacitor at the OSC pin or by driving OSC with an external clock. Both 8-pin DIP and SOIC packages are available in the industrial temperature range. The CAT660 replaces the MAX660 and the LTC660. In addition, the CAT660 is pin compatible with the 7660/ 1044, offering an easy upgrade for applications with 100mA loads.

Note 1. In Figure 1, test circuit capacitors C1 and C2 are 150F and have 0.2 maximum ESR. Higher ESR levels may reduce efficiency and output voltage. Note 2. The output resistance is a combination of the internal switch resistance and the external capacitor ESR. For maximum voltage and efficiency keep external capacitor ESR under 0.2. Note 3. FOSC is tested with COSC = 100pF to minimize test fixture loading. The test is correlated back to COSC=0pF to simulate the capacitance at OSC when the device is inserted into a test socket without an external COSC.

CAT660
The 1/FC1 term can be modeled as an equivalent impedance REQ. A simple equivalent circuit is shown in figure 3. This circuit does not include the switch resistance nor does it include output voltage ripple. It does allow one to understand the switch-capacitor topology and make prudent engineering tradeoffs. For example, power conversion efficiency is set by the output impedance, which consists of REQ and switch resistance. As switching frequency is decreased, REQ, the 1/FC1 term, will dominate the output impedance, causing higher voltage losses and decreased efficiency. As the frequency is increased quiescent current increases. At high frequency this current becomes significant and the power efficiency degrades. The oscillator is designed to operate where voltage losses are a minimum. With external 150F capacitors, the internal switch resistances and the Equivalent Series Resistance (ESR) of the external capacitors determine the effective output impedance. A block diagram of the CAT660 is shown in figure 4. The CAT660 is a replacement for the MAX660 and the LTC660.
APPLICATION INFORMATION
Circuit Description and Operating Theory The CAT660 switches capacitors to invert or double an input voltage. Figure 2 shows a simple switch capacitor circuit. In position 1 capacitor C1 is charged to voltage V1. The total charge on C1 is Q1 = C1V1. When the switch moves to position 2, the input capacitor C1 is discharged to voltage V2. After discharge, the charge on C1 is Q2 = C1V2. The charge transferred is: Q = Q1 - Q2 = C1 x (V1 - V2) If the switch is cycled "F" times per second, the current (charge transfer per unit time) is: I = F x Q = F x C1 (V1 - V2) Rearranging in terms of impedance: I= (V1-V2) (1/FC1) = V1-V2 REQ

OSCILLATOR FREQUENCY CONTROL The switching frequency can be raised, lowered or driven from an external source. Figure 5 shows a functional diagram of the oscillator circuit. The CAT660 oscillator has four control modes: BOOST/FC Pin Connection Open BOOST/FC= V+ Open or BOOST/FC= V+ Open OSC Pin Connection Open Open External Capacitor External Clock Nominal Oscillator Frequency 10kHz 80kHz -- Frequency of external clock an external capacitor at OSC, the operating frequency can be set. Note that the frequency appearing at CAP+ or CAP- is one-half that of the oscillator. Driving the CAT660 from an external frequency source can be easily achieved by driving Pin 7 and leaving the BOOST pin open, as shown in Figure 6. The output current from Pin 7 is small, typically 1A to 8A, so a CMOS can drive the OSC pin. For 5V applications, a TTL logic gate can be used if an external 100k pull-up resistor is used as shown in figure 6.
If BOOST/FC and OSC are left floating (Open), the nominal oscillator frequency is 10kHz. The pump frequency is one-half the oscillator frequency. By connecting the BOOST/FC pin to V+, the charge and discharge currents are increased, and the frequency is increased by approximately 8 times. Increasing the frequency will decrease the output impedance and ripple currents. This can be an advantage at high load currents. Increasing the frequency raises quiescent current but allows smaller capacitance values for C1 and C2. If pin 7, OSC, is loaded with an external capacitor the frequency is lowered.

CAT660
CAPACITOR SELECTION Low ESR capacitors are necessary to minimize voltage losses, especially at high load currents. The exact values of C1 and C2 are not critical but low ESR capacitors are necessary. The ESR of capacitor C1, the pump capacitor, can have a pronounced effect on the output. C1 currents are approximately twice the output current and losses occur on both the charge and discharge cycle. The ESR effects are thus multiplied by four. A 0.5 ESR for C1 will have the same effect as a 2 increase in CAT660 output impedance. Output voltage ripple is determined by the value of C2 and the load current. C2 is charged and discharged at a current roughly equal to the load current. The internal switching frequency is one-half the oscillator frequency. VRIPPLE = IOUT/(FOSC x C2) + IOUT x ESRC2 For example, with a 10kHz oscillator frequency (5kHz switching frequency), a 150F C2 capacitor with an ESR of 0.2 and a 100mA load peak-to-peak ripple voltage is 87mV.

Capacitor manufacturers continually introduce new series and offer different package styles. It is recommended that before a design is finalized capacitor manufacturers should be surveyed for their latest product offerings.
CONTROLLING LOSS IN CAT660 APPLICATIONS There are three primary sources of voltage loss: 1. Output resistance VLOSS = ILOAD x ROUT, where ROUT is the CAT660 output resistance and ILOAD is the load current. 2. Charge pump (C1) capacitor ESR: VLOSSC1 4 x ESRC1 x ILOAD, where ESRC1 is the ESR of capacitor C1. 3. Output or reservoir (C2) capacitor ESR: VLOSSC2 = ESRC2 x ILOAD, where ESRC2 is the ESR of capacitor C2. Increasing the value of C2 and/or decreasing its ESR will reduce noise and ripple. The effective output impedance of a CAT660 circuit is approximately: Rcircuit Rout 660 + (4 x ESRC1) + ESRC2

CASCADE OPERATION FOR HIGHER NEGATIVE VOLTAGES The CAT660 can be cascaded as shown in figure 11 to generate more negative voltage levels. The output resistance is approximately the sum of the individual CAT660 output resistance. VOUT= -N x VIN, where N represents the number of cascaded devices.

PARALLEL OPERATION Paralleling CAT660 devices will lower output resistance. As shown in figure 12, each device requires its own pump capacitor, C2, but the output reservoir capacitor is shared with all devices. The value of C2 should be increased by a factor of N, where N is the number of devices. The output impedance of the combined CAT660's is:
