GENERAL DESCRIPTION OZ529
The OZ529 includes a high effi ciency DC/DC buck converter and a high current USB
power switch for USB port power supply applications.
With current mode DC/DC conversion control and internal compensation, OZ529
provides fast line voltage transient response and minimizes application component
count. The USB power switch employs a proprietary design technique providing out-
put voltage vs. load current compensation and the adaptive buck converter output
voltage control functions to achieve a reliable, fl exible and effi cient solution for high
current USB port power supply applications.
