The OZ8022A/22B/22M are controllers for Buck converters that use quasi-resonant conversion technology. Each can be used to drive high brightness LEDs in offline applications.
OZ8022A/22B/22M provide proprietary Free Dimming technology to control LED brightness using a non-dimming ON/OFF wall switch.
OZ8022A: Three-step forward, 100%-60%-20%, analog dimming control using wall switch
Quasi-resonant converter controller for high brightness LEDs
Low start-up and operating current, maximizing conversion efficiency
Peak current 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 at 19.5V
-Over-voltage for IC bias voltage
Cycle-by-cycle current limit
-LED short circuit
-Output over-voltage and internal Over temperature
