Summary of Features:
  • 500V startup cell for IC self power supply during various states,
  • digital frequency reduction with decreasing load for higher efficiency
  • active burst mode operation for ultra-low standby power (<1W @ 0.5W load)
  • cycle by cylce peak current limitation, maximum output power limitation with input voltage compensation
  • extensive protection features to protect the IC and the system from various fault conditions e.g. output OVP latch, VCC OVP/UVP, OLP, Output OVP, Short-winding, etc.
Benefits:
  • Higher efficiency
  • Low EMI noiseL
  • Low standby power, etc.
Target Applications:
