P6502A

240kHz 23V 2A SYNCHRONOUS DC/DC BUCK CONVERTER

Description

The AP6502A is a 240kHz switching frequency external compensated

synchronous DCDC buck converter. It has integrated low R

DSON

high

and low side MOSFETs.

The AP6502A enables continues load current of up to 2A with efficiency

as high as 95%.

The AP6502A features current mode control operation, which enables

fast transient response times and easy loop stabilization.

The AP6502A 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 AP6502A is available in a standard Green SO-8EP package with

exposed PAD for improved thermal performance and is RoHS

compliant.
