LinkSwitch™-XT energy efficient, low power off-line switcher IC incorporates a 700V power MOSFET, oscillator, simple ON/OFF control scheme, 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. Proprietary IC trimming and transformer construction techniques enable Clampless™ designs with LNK362 for lower system cost, component count and higher efficiency. Self-biased supply saves transformer auxiliary winding and associated bias supply components. It meets HV creepage requirements between DRAIN and all other pins both on the PCB and at the package. Applications include chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio players, shavers, supplies for appliances, industrial systems and metering.
