Power Integrations LNK364PN Flyback Converter 1, Off Liner Power Switch IC 8-Pin, DIP-B

LinkSwitch-XT incorporates a 700 V power MOSFET, oscillator, simple ON/OFF control scheme, a high-voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry onto a monolithic IC. The startup and operating power are derived directly from the DRAIN pin, eliminating the need for a bias winding and associated circuitry.

• Fully integrated auto-restart for short circuit and open loop protection
• Self-biased supply
• Frequency jittering greatly reduces EMI
• Meets HV creepage requirements between DRAIN and all other pins both on the PCB and at the package
• Lowest component count switcher solution Accurate hysteretic thermal shutdown protection
• Universal input range allows worldwide operation
• Simple ON/OFF control, no loop compensation needed
• Auto-restart reduces delivered power by 95% during short circuit and open loop fault conditions
