The package of MA5604 is SOP8L-EP(Exposed pad); the pin assignment is given by:

Name

Description

BS

Boot-Strap Pin. Supply high side gate driver. Decouple this pin to LX pin with 0.1uF

ceramic cap.

IN

Power Input pin. Bypass IN to GND with a suitably large capacitor to eliminate noise on

the input to the IC.

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.

LG

Gate drive for external low side N-MOSFET..

PAD

Ground (Connect to GND).

FB

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

resistive voltage divider from the output voltage.

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.

EN

Enable control. Pull high to turn on. Do not float.

VDD

Internal regulator pin
