GENERAL DESCRIPTION

OZ532 is a controller designed for boost converter LED driver applications. It

integrates a power MOSFET and drives single-string LEDs in applications.

OZ532 provides a compact solution to the applications that require minimum

components for the boost regulator. It is suitable for portable device applica-

tions requiring a single-cell Li-Ion battery.

This IC accepts an external Pulse Width Modulation (PWM) signal to perform

dimming control.
