  Internal Avalanche-Rugged SenseFET (650V)
  Under 50mW Standby Power Consumption at 265VAC, No-load Condition with Burst Mode
  Precision Fixed Operating Frequency with Frequency Modulation for Attenuating EMI
  Internal Startup Circuit
  Built-in Soft-Start: 15ms
  Pulse-by-Pulse Current Limiting
  Various Protections: Over-Voltage Protection (OVP), Overload Protection (OLP), Output-Short Protection (OSP), Abnormal Over-Current Protection (AOCP), Internal Thermal Shutdown Function with Hysteresis (TSD)
  Auto-Restart Mode
  Under-Voltage Lockout (UVLO)
  Low Operating Current: 1.8mA
  Adjustable Peak Current Limit

APPLICATIONs
  SMPS for VCR, STB, DVD, & DVCD Players
