PIN DESCRIPTIONS
Pin No. NAME
Description
1
HSB
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.
2
IN
Power Supply Input. Bypass this pin with a 10µF ceramic capacitor to GND, placed as
close to the IC as possible.
3 SW Power Switching Output to External Inductor.
Ground. Connect this pin to a large PCB copper area for best heat dissipation. Return FB,
4 GND COMP, and ISET to this GND, and connect this GND to power GND at a single point for
best noise immunity.
5
FB
Feedback Input. The voltage at this pin is regulated to 0.800V. Connect to the resistor
divider between output and GND to set the output voltage.
6 LCOMP Output cable resistance compensation.
OVP input. Overvoltage protection. The turnover voltage at this pin is 1.25V. The OVP
7 OVP circuit will turn off the PWM and cause the output floating until the voltage of OVP lower
than 1.25V.
8
ISET
Output Current Setting Pin. Connect a resistor from ISET to GND to program the output
current.
Exposed Heat Dissipation Pad. Connect this exposed pad to large ground copper area with copper
Pad and vias.
