TinySwitch-III incorporates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design fl exible solution with a low system cost and extended power capability.
1. Lowest System Cost with Enhanced Flexibility
2. Simple ON/OFF control, no loop compensation needed
3. Selectable current limit through BP/M capacitor value
4. Higher current limit extends peak power or, in open frame applications, maximum continuous power
5. Lower current limit improves effi ciency in enclosed adapters/chargers
1. Chargers / adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.
2. PC Standby and other auxiliary supplies
3. DVD/PVR and other low power set top decoders
4. Supplies for appliances, industrial systems, metering, etc.
