DK124
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
