Overview

L6699 Enhanced high voltage resonant controller.

Key Features

  • Symmetrical duty cycle, variable frequency control of resonant half bridge.
  • Self-adjusting adaptive deadtime.
  • High-accuracy oscillator.
  • 2-level OCP: frequency-shift and immediate shutdown.
  • Interface with PFC controller.
  • Anti-capacitive-mode protection.
  • Burst-mode operation at light load.
  • Input for brownout protection or power-on/off sequencing.
  • “Safe-start” procedure prevents hard switching at startup.
  • 600 V rail compatible high-side gate driver.
