OZ9965

GENERAL DESCRIPTION

The OZ9965 is a wide input range, multi-output, power management control-

ler for small panel LCD applications. It controls the DC/DC power conversion

from a single input supply voltage to provide the power needed to drive an LED

backlight module, source drivers and gate drivers used in a LCD application.

OZ9965 includes a high power LED driver controller, a boost converter, and one

general purpose converter that can be configured into either a buck or negative

buck-boost converter.
