Fixed Frequency Flyback Controller with Ultra-low No Load Power Consumption

Features & Benefits

  • Fixed-frequency current-mode control with internal slope compensation
  • Frequency foldback down to 25kHz at light loads
  • Burst mode for low standby power consumption, meeting EuP Lot 6
  • Frequency jitter to reduce EMI signature
  • X-cap discharge function
  • Adjustable overpower compensation
  • Internal high-voltage current source
  • VCC under-voltage lockout with hysteresis (UVLO)
  • Brown-out protection on HV
  • Overload protection with programmable delay
  • Thermal shutdown (auto-restart with hysteresis)
  • Latch-off for external over-voltage protection (OVP) and over-temperature protection (OTP) on TIMER
  • Latch-off for Vcc over voltage protection
  • Short-circuit protection
  • Programmable soft start
