  • Up to 95% efficiency.
  • Pulse energy mode for high light load efficiency (Vin=12V, Vo=5V, 89% @10mA).
  • Output voltage adjustable to 0.8V.
  • 3A continuous output current.
  • 750kHz PWM operation.
  • Internal compensation.
  • Internal Soft Start.
  • Cycle-by-cycle current limit.
  • Pre-bias start-up.
  • Short-circuit protection.
