AP6503A
240kHz 23V 3A SYNCHRONOUS DC/DC BUCK CONVERTER
Description
Pin Assignments
The AP6503A is a 240kHz switching frequency external compensated
synchronous DC-DC buck converter. It has integrated low RDS(ON) high
and low-side MOSFETs.
(Top View)
The AP6503A enables continuous load current of up to 3A with
efficiency as high as 95%.
The AP6503A features current mode control operation, which enables
fast transient response time and easy loop stabilization.

The AP6503A simplifies board layout and reduces space requirements
with its high level of integration and minimal need for external
components, making it ideal for distributed power architectures.
The AP6503A is available in a standard Green SO-8EP package with
exposed PAD for improved thermal performance and is RoHS
compliant.
