P65200

LIGHT LOAD IMPROVED 2A SYNCH DC/DC BUCK CONVERTER

Description

The AP65200 is a 340kHz switching frequency external compensated

synchronous DC/DC buck converter. It has integrated low R

DSON

high

and low side MOSFETs.

The AP65200 enables continues load current of up to 2A with

efficiency as high as 95%.

The AP65200 implements an automatic custom light load

efficiency improvement algorithm.

The AP65200 features current mode control operation, which enables

fast transient response times and easy loop stabilization.

The AP65200 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 AP65200 is available in a standard Green SO-8, MSOP-8EP,

U-DFN2626-10 and SO-8EP package and is RoHS compliant.
