The LinkSwitch-XT family provides very low power AC-DC power conversion.
700 V Internal MOSFET Rating Self-Powered ON/OFF Control Hysteretic Overtemperature Protection Power Limiting Frequency Jitter Reduces EMI EcoSmart® Low Standby/No-load Power Consumption
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
