SHENZHEN DONGKE SEMICONDUCTOR CO., LTD SMALL POWER OFF-LINE SWITCH MODE POWER CONTROLLER -DK1203 SPECIFICATION 1. DESCRIPTION
The DK1203 is a secondary side flyback type AC-DC Switch Mode Power Controlling IC. With integrated 700V high voltage power transistor,patented self-power suppl y circuit and integrated MOS circuit design, lots of external components are sav ed, transformer design is simple, only two windings is needed for the transforme r in isolated output circuit.
2. APPLICATIONS
·AC/DC power adapters ·DVD/VCD power supply ·Air conditioner power supply · Electromagnetic oven power supply ·DVB power supply · LED driver applications ·TV/Monitor power supply
3. MAIN FEATURES
· 85V—265V wide range AC power input. · Build-in 700V power transistor. · Internal integrated high voltage starting circuit, no need for additional resistance. · Integrated self-start circuit. · Pulse-Width Modulation (PWM) controlled system. · VCC operating voltage range: 4-6V. · 65kHz switching frequency. · Automatically turn to skip cycle mode under light load condition. · Over current, Over loading, Over temperature and Over voltage Protection. · Standby power consumption lower then 0.3W. · Internal frequency modulation circuit to reduce EMI filter cost.
4. POWER RANGE Input Voltage
85-265V AC 85-145V AC 180-265V AC
MAX. output power
