General Description
The XC9504 series are PWM control, PWM/PFM switching, 2 channel (step-up and inverting) DC/DC controller ICs. With 0.9V of standard voltage supply internal, and using externally connected components, the output 1 voltage (step-up DC/DC controller) can be set freely within a range of 1.5V ~ 30V. Since output 2 (inverting DC/DC controller) has a built-in 0.9V reference voltage (accuracy 2), a negative voltage can be set with the external components. With a 180kHz frequency, the size of the external components can be reduced. Switching frequencies of 300kHz and 500kHz are also available as custom-designed products. The control of the XC9504 series can be switched between PWM control and PWM/PFM automatic switching control using external signals. Control switches from PWM to PFM during light loads when automatic switching is selected and the series is highly efficient from light loads through to large output currents. Noise is easily reduced with PWM control since the frequency is fixed. The series gives freedom of control selection so that control suited to the application can be selected. Soft-start time is internally set to 10msec (output 1) which offers protection against rush currents and voltage overshoot when the power is switched on .

Notes

2ch. Step-up / Inverting DC/DC Controller ICs
Although the IC's step-up operations start from a VDD of 0.8V, the output voltage and switching frequency are stabilized at VDD 2.0V. Therefore, a VDD of more than 2.0V is recommended when VDD is supplied from VIN or other power sources. Although the IC's switching operations start from a VIN of 0.9V, the IC's power supply pin (VDD) and output voltage monitor pin (FB1) should be connected to VOUT1. With operations from VIN=0.9V, the 2nd channel's (output 2) EN2 pin should be set to chip disable. Once ouput voltage VOUT1 is more than 2.0V, the EN2 pin should be set to chip enable. Please be careful not to exceed the breakdown voltage level of the peripheral parts. EFFI={ [ (Output voltage) x (Output current) ] / [ (Input voltage) x (Input Current) ] } x 100

Operational Description
2ch. Step-up / Inverting DC/DC Controller ICs
The XC9504 series are dual DC/DC (step-up + inverting) converter controller ICs with built-in high speed, low ON resistance buffers. Error Amplifier 1 is designed to monitor the output voltage and it compares the feedback voltage 1 (FB1) with the reference voltage Vref1. In response to feedback of a voltage lower than the reference voltage Vref1, the output voltage of the error amp. decreases. Error Amplifier 2 is designed to monitor the output voltage and it compares the feedback voltage 2 (FB2) with the reference voltage Vref 2. In response to feedback of a voltage lower than the reference voltage Vref2, the output voltage of the error amp. decreases. This circuit generates the internal reference clock. The Ramp Wave Generator generates a saw-tooth waveform based on outputs from the OSC Generator. The PWM Comparator compares outputs from the Error Amp. and saw-tooth waveform. When the voltage from the Error Amp's output is low, the external switch will be set to ON. This circuit generates PFM pulses. Control can be switched between PWM control and PWM/PFM automatic switching control using external signals. The PFM/PWM automatic switching mode is selected when the voltage of the PWM1 (2) pin is less than 0.2V, and the control switches between PWM and PFM automatically depending on the load. As the PFM circuit generates pulses based on outputs from the PWM Comparator, shifting between modes occurs smoothly. PWM control mode is selected when the voltage of the PWM1 (2) pin is more than 0.65V. Noise is easily reduced with PWM control since the switching frequency is fixed. Control suited to the application can easily be selected which is useful in audio applications, for example, where traditionally, efficiencies have been sacrificed during stand-by as a result of using PWM control (due to the noise problems associated with the PFM mode in standby).
The reference voltage, Vref1(FB1 pin voltage)=0.9V, is adjusted and fixed by laser trimming (for output voltage settings, please refer to the functional settings notes on page 9.). To protect against inrush current, when the power is switched on, and also to protect against voltage overshoot, soft-start time is set internally to 10ms. It should be noted, however, that this circuit does not protect the load capacitor (CL) from inrush current. With the Vref voltage limited, and depending upon the input to error amp 1, the operation maintains a balance between the two inputs of error amps and controls the EXT pin's ON time so that it doesn't increase more than is necessary.
The reference voltage, Vref2 (FB2 pin voltage)=0.9V, is adjusted and fixed by laser trimming. This function controls the operation and shutdown of the IC. When the voltage of the EN1 or EN2 pins is 0.2V or less, the mode will be disable, the channel's operations will stop and the EXT1 pin will be kept at a low level (the external N-type MOSFET will be OFF) and the EXT2 pin will be kept at a high level (the external P-type MOSFET will be OFF). When both EN1 and EN2 are in a state of chip disable, current consumption will be no more than 3.0A. When the EN1 or EN2 pin's voltage is 0.65V or more, the mode will be enable and operations will recommence. With channel one (output 1) soft-start, 95% of the set output voltage will be reached within 10msec (TYP) from the moment of enable.

< Output Voltage Setting, Ch.1 (Step-up DC/DC Converter Controller) > Output voltage can be set by adding external split resistors. Output voltage is determined by the following equation, based on the values of RFB11 and RFB12. The sum of RFB11 and RFB12 should normally be 1 M or less. VOUT1=0.9 x (RFB11+RFB12) / RFB12 The speed-up capacitor for phase compensation's (CFB1) value should be adjusted using the formula fzfb=1/(2xxCFB1xRFB11) so that it equals 12kHz. Depending on the application, the inductance value L, and the load capacity value CL, adjustments to this value are suggested so that the value is somewhere between 1kHz to 50kHz. [Calculation Example] When RFB11=470k and RFB12=30k : VOUT1=0.9 x (470k+30k) / 30k=15.0V. [Typical Example]

Output voltage is determined using the following equation and is based on the values of RFB21 and RFB22. The sum of RFB21 and RFB22 should normally be 500k or less. The equation uses Ch 1's (VOUT1) output voltage calculation method for the reference voltage. VOUT2 = (0.9 - VOUT1) x (RFB21 / RFB22) + 0.9V [Calculation Example] When RFB21=17.5k, RFB22=10k, VOUT1=3.3V, VOUT2= - 3.3V The value of speed-up capacitor for phase compensation CFB21 : [Conditions: Heavy load (when coil current is continous.)] fzfb2 = 1/2 x x CFB21 x RFB21) = 10kHz Depending on the application, the inductance value L, and the load capacity value CL, adjustments to this value are suggested so that the value is somewhere between 1kHz to 50kHz.

Notes on how to use
Hint on application
2ch. Step-up / Inverting DC/DC Controller ICs
1. Channel 1 (step-up) How to shut down the output voltage during standby mode If the circuit configuration shown as an example of typical application circuits is used, voltage VIN will occur at VOUT 1 when the IC is in standby, the diode being bypassed. This can cause circuits connected to VOUT 1 to malfunction.
> Example of typical application circuit 1 :
VOUT1 Pch MOSFET1 R1 CFB1 Nch MOSFET2 RFB12 ON/OFF signal FB1 EN1 SBD1
Set R1 so as to prevent leakage current of N-ch MOSFET 2.

> Example of typical application circuit 2 : Power Ready Function
VOUT1 Pch MOSFET1 R1 CFB1 RFB11 NPN Bip1 C1 Nch MOSFET2 ON/OFF signal R2 CL1 RFB12 Inside of XC9504 IC FB1 SBD1
The combination of R 2, C 1, and the threshold voltage of approximately 0.7 V of NPN Bip 1 is used to produce a delay time between the circuits being enabled and P-ch MOSFET 1 being switched on. Delay time set to 20 mS ensures power to be made ready in a favorable manner, as soft start of this product is completed during the delay time. Set Value (Example)
VOLTAGE (V) 2.5 3.3 5.0 R2 (k) 430 470 430 C1 (F) 0.15 0.18 0.33
EN1
Time to make power ready is calculated by the equation below. Time = - R2 x C1 x Ln (1 - 0.7 / [ON / OFF Signal Voltage ] Set R1 so as to prevent leakage curren tof NPN (Bip 1). Nch MOSFET 2 and the inverter enables power to be turned off quickly. Soft start circuit 2. Channel 2 ( Inverting ) Channel 2 (inverting) is subject to the overshoot of output voltage 2 (VOUT 2) at start-up. It is possible to control the overshoot of output voltage 2 (VOUT 2), as shown by circuit example 1 in "Output Voltage Settings for Channel 2" in "Function Settings." In this circuit configuration, EN 1 and EN 2 are enabled (set to "H" level) simultaneously. This lets output voltage 1 (VOUT 1) of channel 1 increase gently as soft start, thereby controlling the overshoot. > Example of typical application circuit : Improved Soft start This example is effective when EN 1 and EN 2 are enabled with different timings under light load condition (the coil current being discontinuous). Time to make soft start time is calculated by the equation below.
VOUT1 Inside of XC9504 IC R1 RFB22 FB2 EN2 ON/OFF signal SBD2 CL2 RFB21 CFB21 Pch MOSFET1
Time SS2 = - R FB21 x C CFB21 / Ln
1-
(0.9 - V OUT2 ) x R FB22 ) (V OUT1 - 0.9) x R FB21
Nch MOSFET2
VOUT2
Example ) When VOUT1 = 15V and VOUT2 = - 7.5V, RFB21 = 59.6k, RFB22 = 100k by the equation below. VOUT2 = (0.9 - VOUT1) x (RFB21 / RFB22) + 0.9 When the light load, CFB21=0.1F or lower value can be used. Therefore, when CFB21=0.027F, Time_ss2 = 5.0mS and VOUT2 = 95% of setting value
3. Channel 2 (Inverting) Withstand voltage of transistor The voltage applied between the drain and source is the sum of VIN and VOUT 2. Select a transistor with an absolute VDSS rating that is suitable for your operating conditions. Example: The voltage applied across VDS of a transistor will be 20.0V if VIN = 5.0 V and VOUT 2 = -15.0 V. Under this condition, a transistor with VDSS higher than 20.0V should be selected. (Use a transistor with VDSS that is 1.5 times the applied voltage or more, as a standard.)

Note on Use
2ch. Step-up / Inverting DC/DC Controller ICs
1. PWM/PFM Automatic Switching If PWM/PFM automatic switching control is selected and the step-up ratio is low (e.g., from 4.5 V to 5.0 V), the control mode remains in PFM setting over the whole load range, since the duty ratio under continuous-duty condition is smaller than the PFM duty ratio of the XC9504 series. The output voltage's ripple voltage becomes substantially high under heavy load conditions, with the XC9504 series appearing to be producing an abnormal oscillation. If this operation becomes a concern, set pins PWM to High to set the control mode to PWM setting. For use under the above-mentioned condition, measured data of PWM/PFM automatic switching control shown on the data sheets are available up to IOUT = 100 mA.
2. Ratings Use the XC9504 series and peripheral components within the limits of their ratings.
