Key features
  • 800 V avalanche-rugged power MOSFET allowing achieving ultra wide-range input Vac
  • Embedded HV startup and sense FET
  • PWM current-mode controller
  • OCP with selectable threshold (IDlim) and 2ndOCP with higher value (IDMAX) to protect the IC from transformer saturation or short-circuit of the secondary diode
  • 30 mW no-load consumption at 230 Vac
  • Two operating frequencies:
    • 60 kHz (L type) or 115 kHz (H type)
  • Jittered frequency reduces the EMI
  • Extra power timer (EPT) blanks the overload current for few seconds
  • Output overvoltage protection with tight tolerance and digital noise filter
  • Soft-start reduces the stress during startup and increases IC lifetime
  • Automatic restart after a fault condition
  • Thermal shutdown increases system reliability and IC lifetime
