P65500

LIGHT LOAD IMPROVED 5A SYNCH DC/DC BUCK CONVERTER

Description

The AP65500 is a 340kHz switching frequency external compensated

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

DSON

high

and low side MOSFETs.

The AP65500 enables continues load current of up to 5A with

efficiency as high as 96%.

The AP65500 implements an automatic custom light load

efficiency improvement algorithm.

The AP65500 features current mode control operation, which enables

fast transient response times and easy loop stabilization.

The AP65500 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 AP65500 is available in a standard Green SO-8EP package and

is RoHS compliant.
