Pin #

Symbol

HSB

Function

High Side Bias Pin. This provides power to the internal high-side MOSFET

gate driver. Connect a 22nF capacitor from HSB pin to SW pin.

Power Supply Input. Bypass this pin with a 10μF ceramic capacitor to GND,

placed as close to the IC as possible.

Power Switching Output to External Inductor.

Ground. Connect this pin to a large PCB copper area for best heat dissipation.

Return FB, COMP, and I_SETto this GND, and connect this GND to power GND

at a single point for best noise immunity.

GND

Feedback Input. The voltage at this pin is regulated to 800mV. Connect to the

resistor divider between output and GND to set the output voltage.

Error Amplifier Output. This pin is used to compensate the converter.

OVP input. If the voltage at this pin exceeds 0.8V, the IC shuts down high side

switch. There is a 2μA pull-up current at this pin.

COMP

OVP

Output Current Setting Pin. Connect a resistor from I_SETto GND to program

the output current.

I_SET

Exposed

Pad

Heat Dissipation Pad. Connect this exposed pad to large ground copper area

with copper and vias.
