LNK3604P

LinkSwitch™-XT2 incorporates a 725V/900V 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 start-up and operating power are derived directly from the DRAIN pin, eliminating the need for a bias winding and associated circuitry.

• Lowest component count switcher solution
• Selectable device current limit
• Fully integrated auto-restart for short-circuit and open-loop protection
• Optional self-biased supply
• Pin-out simplifies PCB heat sinking
• Hysteretic over-temperature protection
• Input overvoltage line protection
• Extended creepage between DRAIN pin and all other pins improves field reliability
• 725V MOSFET rating series for excellent surge withstand
• EcoSmart™ - Extremely Energy-Efficient
