AP65503 Datasheet

AP65503 LIGHT LOAD IMPROVED 5A 750kHz SYNCH DC/DC BUCK CONVERTER

The AP65503 is a 750kHz switching frequency external compensated synchronous DC/DC buck converter. It has integrated low RDSON high and low side MOSFETs. The AP65503 enables continues load current of up to 5A with efficiency as high as 96%. The AP65503 implements an automatic custom light load effic.

Features

current mode control operation, which enables fast transient response times and easy loop stabilization. The AP65503 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 AP65503 is available in a standard Green SO-8EP package and is RoHS compliant. Pin Assignments Features
