AP65200
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 RDS(ON)
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.
