DESCRIPTION
Low-side MOSFET gate driver output. Connect to the gate terminal of the low-side MOSFET of
the converter.
Return current path for the LGATE MOSFET driver. Connect to the source of the low-side MOSFET.
IC ground for bias supply and signal reference.
Enable input for the IC. Pulling EN above the V ENTHR rising threshold voltage initializes the
soft-start sequence.
Logic input for setpoint voltage selector. Use in conjunction with the VID0 pin to select among four
setpoint reference voltages.
Logic input for setpoint voltage selector. Use in conjunction with the VID1 pin to select among
four setpoint reference voltages. External reference input when enabled by connecting the
SET0 pin to the VCC pin.
Soft-start and voltage slew-rate programming capacitor input. Setpoint reference voltage
programming resistor input. Connects internally to the inverting input of the V SET voltage
setpoint amplifier.
Voltage set-point programming resistor input.
Voltage set-point programming resistor input.
Voltage set-point programming resistor input.
Power-good open-drain indicator output. This pin changes to high impedance when the
converter is able to supply regulated voltage. The pull-down resistance between the PGOOD
pin and the GND pin identifies which protective fault has shut down the regulator.
Voltage feedback sense input. Connects internally to the inverting input of the control-loop
error amplifier. The converter is in regulation when the voltage at the FB pin equals the voltage
on the SREF pin. The control loop compensation network connects between the FB pin and the
converter output.
Output voltage sense input for the R 3 modulator. The VO pin also serves as the reference input
for the overcurrent detection circuit.
