TNY278PN Datasheet

AC/DC Switching Converters


The TNY278PN is 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 flexible solution with a low system cost and extended power capability. TNY278PN Features &bull; Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset&bull; Improved auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions&bull; Output overvoltage shutdown with optional Zener&bull; Line under-voltage detect threshold set using a single optional resistor&bull; Very low component count enhances reliability and enables single-sided printed circuit board layout&bull; High bandwidth provides fast turn on with no overshoot and excellent transient load response&bull; Extended creepage between DRAIN and all other pins improves field reliability TNY278PN Applications &bull; Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.&bull; PC Standby and other auxiliary supplies&bull; DVD/PVR and other low power set top decoders&bull; Supplies for appliances, industrial systems, metering, etc.
