TNY279PN Datasheet PDF – Off-Line Switcher

Part Number: TNY279PN

Function: Enhanced / Energy Efficient / Low Power Off-line Switcher

Package: DIP 8 Pin

Manufacturer: Power Integrations, Inc


TNY279PN datasheet


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.




Enhanced Safety and Reliability Features

1. Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset
2. Improved auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions
3. Output overvoltage shutdown with optional Zener
4. Line under-voltage detect threshold set using a single optional resistor


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.
