OZ8022V

FEATURES

• Quasi-resonant converter controller for high brightness LEDs

• Supports high power factor for LED lighting applications

• Low start-up and operating current, maximizing conversion efficiency

• Voltage-mode control simplifies circuit design

• Under-voltage lockout with hysteresis

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

• Provides complete protection functions:

- Maximum gate drive output and clamp

- Over-voltage for IC bias voltage

- Cycle-by-cycle current limit

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

GENERAL DESCRIPTION

The OZ8022V is a controller for Buck converters that use quasi-resonant con-

version 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 modes of inductor current.
