AP66300

Description

The 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.

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.
