功能特点

POWER MANAGEMENT ICs

The OZ529 includes a high efficiency DC/DC buck converter and a high current 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.
