Key Features

  • Switch-mode buck controller that drives strings of LEDs up to 600 V power-efficiently.
  • Controller with power-efficient Boundary Conduction Mode (BCM) operation: ‹ Virtually no reverse recovery losses in freewheel diode ‹ Zero Current Switching (ZCS) at switch, switch-on ‹ Zero voltage or valley switching at switch, switch-on ‹ Minimal required inductance value and size.
  • Suitable for direct Pulse Width Modulation (PWM) dimming.
  • Fast transient response through.
