OZ8022T

FEATURES

• Three-step analog dimming control using wall switch

• Supports high power factor and low THD for residential and commercial

lighting applications

• Quasi-resonant converter controller for high brightness LEDs

• Built-in high voltage start-up circuit

• 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 OZ8022T is a controller for Buck converters that use quasi-resonant con-

version technology. It can be used to provide regulated current for high bright-

ness LEDs with power factor correction in offline applications.

OZ8022T provides proprietary Free Dimming technology to control LED bright-

ness using a non-dimming ON/OFF wall switch.
