AP66300 Datasheet 3a Low Iq Synchronous Buck Converter

Manufacturer: Diodes Incorporated

Overview: ADVANCED INFORMATION AP66300 3.8V TO 60V INPUT, 3A LOW IQ SYNCHRONOUS BUCK.

General Description

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.

Key Features

  • current mode control operation, which enables easy loop stabilization supporting wide range of output capacitive loads. 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. The AP66300 is available in a standard Green U-QFN4040-16/SWP (Type UXB) package. Pin Assignments 16 15 14 BIAS 1 VCC 2 VIN 3 VIN 4 EPAD 5 6 7 GND FB SS/TR PG 13 12 MSYNC 1.
