Functional Pin Descriptions  
VSEN1 (Pin 19)  
PHASE (Pin 23)  
This pin is connected to the PWM converter’s output voltage.  
The PGOOD and OVP comparator circuits use this signal to  
report output voltage status and for over voltage protection.  
Connect the PHASE pin to the PWM converter’s upper  
MOSFET source. This pin is used to monitor the voltage  
drop across the upper MOSFET for over-current protection.  
OCSET (Pin 20)  
UGATE (Pin 24)  
Connect a resistor (R  
) from this pin to the drain of the

Connect UGATE pin to the PWM converter’s upper MOSFET  
gate. This pin provides the gate drive for the upper MOSFET.

LGATE (Pin 22)

gate. This pin provides the gate drive for the lower MOSFET.

r
DS(ON)  
An over-current trip cycles the soft-start function. Sustaining  
an over-current for 2 soft-start intervals shuts down the  
controller.  
VCC (Pin 1)  
Provide a 12V bias supply for the IC to this pin. This pin also  
provides the gate bias charge for all the MOSFETs  
controlled by the IC.  
SS (Pin 9)  
Connect a capacitor from this pin to ground. This capacitor,  
along with an internal 11µA (typically) current source, sets  
the soft-start interval of the converter.  
RT (Pin 10)  
This pin provides oscillator switching frequency adjustment.  
By placing a resistor (R ) from this pin to GND, the nominal  
200kHz switching frequency is increased according to the  
following equation:  
T
Pulling this pin low with an open drain signal will shut down  
the IC.  
VID0, VID1, VID2, VID3, VID4 (Pins 6, 5, 4, 3 and 2)  
VID0-4 are the input pins to the 5-bit DAC. The states of  
these five pins program the internal voltage reference  
(DACOUT). The level of DACOUT sets the core converter  
output voltage. It also sets the core PGOOD and OVP  
thresholds.

Conversely, connecting a pull-up resistor (R ) from this pin

following equation:  
COMP and FB (Pins 17 and 18)

4 × 10  
COMP and FB are the available external pins of the PWM  
error amplifier. The FB pin is the inverting input of the error  
amplifier. Similarly, the COMP pin is the error amplifier  
output. These pins are used to compensate the voltage-  
control feedback loop of the PWM converter.

FAULT (Pin 8)  
This pin is low during normal operation, but it is pulled to VCC  
in the event of an over-voltage or over-current condition.  
GND (Pin 14)  
Signal ground for the IC. All voltage levels are measured with  
respect to this pin.  
GATE3 (Pin 15)  
Connect this pin to the gate of an external MOSFET. This pin  
provides the drive for the linear controller’s pass transistor.  
PGOOD (Pin 7)  
VSEN3 (Pin 16)  
Connect this pin to V  
regulated to 1.5V.  
PGOOD is an open collector output used to indicate the  
status of the output voltages. This pin is pulled low when the  
core output is not within ±10% of the DACOUT reference  
voltage and the other outputs are below their under-voltage  
thresholds.
