Pin Description
Pin Name
Description
1
PGood
Power Good status pin. Output is open collector. Connect a pull up
resistor from this pin to Vcc.
2
Vcc
This pin provides biasing voltage for the internal blocks of the IC. It also
biases the low side driver. A minimum of 0.1uF, high frequency capacitor
must be connected from this pin to power ground.
3
LDrv
Output driver for the low side MOSFET
4
PGnd
Power Ground. This pin serves as a separate ground for the MOSFET
drivers and should be connected to the system’s power ground plane.
5
HDrv
Output driver for the high side MOSFET
6
Vc
This pin powers the high side driver and must be connected to a voltage
higher than bus voltage. A minimum of 0.1uF, high frequency capacitor
must be connected from this pin to power ground.
7
Vsns
PGood sense pin
8
Fb
Inverting input to the error amplifier. This pin is connected directly to the
output of the regulator via resistor divider to set the output voltage and
provide feedback to the error amplifier.
9
Comp
Output of the error amplifier.
10
Gnd
Signal ground for internal reference and control circuitry.
11
SS/SD
Soft start / shutdown. This pin provides user programmable soft-start
function. Connect an external capacitor from this pin to ground to set the
start up time of the output voltage. The converter can be shutdown by
pulling this pin below 0.3V.
12
OCSet
Current limit set point. A resistor from this pin to drain of the low side
MOSFET will set the current limit threshold.
