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.
