Introduction

DK124 is an off-line switching power supply chip, the maximum output power of 24W. Unlike the PWM controller and the external discrete power MOS combination solution, the DK124 integrates a PWM controller, a 700V power transistor and a primary peak current detection circuit, and uses a patented self-powered technology that can omit the auxiliary supply winding, Simplifies peripheral applications, reduces the number of originals, circuit size and weight, especially for cost-sensitive flyback switching power supplies.

Features

85V—265V wide range AC power input.
Build-in 700V power transistor.
Internal integrated high voltage starting circuit, no need for additional resistance.
Internal 16mS soft-start circuit.
Internal power compensation circuit to keep the stability of max. output power in both high and low voltage.
Patent dynamic self-power supply, no need for auxiliary winding.
Internal frequency modulation circuit to reduce EMI filter cost.
Over current, Over loading, Over temperature, Over voltage and Short circuit Protection.

Applications

Battery charger 
DVD/VCD/VCR power supply
Power AC/DC adapters
Air conditioner power supply
STB power supply
LED driver applications
Electromagnetic oven power supply
TV/Monitor power supply
