O2 Micro International Ltd OZ8023

Industrial/Automotive Applications

Overview

TopologyFlyback Converter
Input voltage90-264 V

Description

The OZ8023 is a voltage-mode, quasi-resonant converter controller, suitable for offline, AC/DC flyback converter applications. It can be used as a single-stage power factor correction controller for an isolated power supply or LED driver applications.

The OZ8025 is a controller for an isolated LED driver application. It provides a proprietary 3-level dimming control to LEDs using an ON/OFF wall switch.

Features

  • Quasi-resonant converter controller

  • Built-in high-voltage startup circuit

  • Voltage-mode control simplifies circuit design

  • Under-voltage lockout with hysteresis

  • Minimum off-time control for light-load operation, maximizing efficiency

  • Excellent line-voltage regulation

  • Provides complete protectionfunctions:

  • Clamped gate drive output

  • Over-voltage for IC bias voltage

  • Cycle-by-cycle current limit

  • Output short circuit; over load;output over-voltage; and internalover-temperature

Typical applications

  • Isolated LED Driver
