  • Consumes only 0.65W at 240VAC & 0.3W load with Advanced Burst-Mode Operation.
  • Frequency Modulation for EMI Reduction.
  • Precision Fixed Operating Frequency.
  • Internal Start-up Circuit.
  • Pulse-by-Pulse Current Limiting.
  • Abnormal Over Current Protection (AOCP).
  • Over Voltage Protection (OVP).
  • Over Load Protection (OLP).
  • Internal Thermal Shutdown Function (TSD).
  • Auto-R.
