Name

Description

SW

Power Switching Output. SW is the switching node that supplies power to the output.

Connect the output LC filter from SW to the output load.

VIN

Power Input. Bypass VIN to Ground with a suitably high capacitance E-CAP to eliminate

noise, and bypass IC PIN2-VIN to pin8-GND with a 4.7uf ceramic MLCC (e.g. X5R.)

HGC Supply high-side gate driver. Decouple this pin to VIN pin with 0.1uf ceramic CAP (e.g.

X5R) and an 18kΩ resistor.

EN

Enable control. ( internal pull high ).

COMP Compensation Node. COMP is used to compensate the regulation control loop. Connect a

series RC network from COMP to GND to compensate the regulation control loop.

FB

Feedback Input. FB senses the output voltage to regulate that voltage. Drive FB with a

resistive voltage divider from the output voltage.

VDD

Internal regulator pin.

GND Ground.

PAD

SW (Connect to SW).
