AP66300Q

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

Description

Pin Assignments

The DIODES™ AP66300Q 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.

BIAS

VCC

VIN

MSYNC

The device enables a continuous load current of up to 3A with

efficiency as high as 95% in enhanced biased. It features current

mode control operation, which enables easy loop stabilization

supporting a wide range of output capacitive loads.

10 EN

EPAD

The AP66300Q 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.

VIN

PGND

The AP66300Q is available in the standard Green U-QFN4040-

16/SWP (Type UXB) package.
