AP66300

3.8V TO 60V INPUT, 3A LOW IQ SYNCHRONOUS BUCK CONVERTER

Description

Pin Assignments

The DIODES™ AP66300 is an adjustable switching frequency

internal compensated synchronous DC-DC buck converter with a

default internal frequency of 500kHz. The device fully integrates a

120mΩ high-side power MOSFET and a 55mΩ low-side power

MOSFET to provide high-efficiency step-down DC-DC conversion.

The AP66300 enables continuous load current of up to 3A with

efficiency as high as 95% in enhanced biased.

The AP66300 features current mode control operation, which

enables easy loop stabilization supporting wide range of output

capacitive loads.

10 EN

The AP66300 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.
