TopologieAbwärtswandler
Eingangsspannung85-265 V
Ausgang 180 V / 0.22 A

Beschreibung

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.

Eigenschaften

  • 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

Typische Anwendungen

  • LED Driver
