O2 Micro International Ltd OZ8022V

Description

The OZ8022V is a controller for Buck converters that uses quasi-resonant conversion technology. It can be used to drive high-brightness LEDs, with power factor correction, in offline applications. The Buck converter operates between the continuous and discontinuous mode of inductor current.

Features

• Quasi-resonant converter controller for high-brightness LEDs
• Low stand-by and operating current
• Peak current-mode control simplifies circuit design
• Under-voltage lockout with hysteresis
• Minimum off-time control at high-input voltage operation condition

• Provides complete protection functions:

  -Maximum gate drive output-Over-voltage for IC bias voltage-Cycle-by-cycle current limit

  -LED short circuit; output over-voltage; and internal over temperature

Typical applications

• LED Driver
