Overview

The DK124 is a secondary side fly-back type AC-DC Switch Mode Power Controlling IC. Designed with high integration CMOS circuit, it has protection functions for short circuit, secondary side open circuit, over temperature, over voltage and so on.

  • 90V-265V wide range AC power input.
  • Built-in 700V HV BJT
  • Internal integrated high voltage starting circuit, no need for additional resistance
  • Burst mode (22kHz Intermittent operation mode)
  • Standby power consumption < 0.3W
  • 65KHz PWM switching frequency
  • 4KV ESD
  • Internal power compensation circuit to keep the stability of output in different input situation
  • Patented self-power supply design, no need for auxiliary winding in transformer
  • Internal frequency modulation circuit to reduce EMI filter cost
