GENERAL DESCRIPTION

The OZ529 includes a high efficiency DC/DC buck converter and a high cur-

rent USB power switch designed for USB port power supply applications. With

current mode DC/DC conversion control and internal compensation, OZ529

provides fast line voltage transient response to minimize application component

count.

The USB power switch employs a proprietary design technique that provides

output voltage vs. load current compensation. The adaptive buck converter

output voltage control achieves a reliable, flexible and efficient solution for high

current USB port, power supply applications.
