Product Summary
The TNY290PG is an Energy-Efficient, Off-Line Switcher With Enhanced Flexibility and Extended Power Range. The TNY290PG incorporates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The TNY290PG uses an ON/OFF control scheme and offers a design fl exible solution with a low system cost and extended power capability. The applications of the TNY290PG include Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc, PC Standby and other auxiliary supplies, DVD/PVR and other low power set top decoders and Supplies for appliances, industrial systems, metering, etc.
Parametrics
TNY290PG absolute maximum ratings: (1)DRAIN Voltage: -0.3 V to 700 V; (2)DRAIN Peak Current: 1040 (1950) mA; (3)EN/UV Voltage: -0.3 V to 9 V; (4)EN/UV Current: 100 mA; (5)BP/M Voltage: -0.3 V to 9 V; (6)Storage Temperature: -65 to 150℃; (7)Operating Junction Temperature: -40 to 150℃; (8)Lead Temperature: 260℃.
Features
TNY290PG 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 undervoltage detect threshold set using a single optional; (5)resistor; (6)Very low component count enhances reliability and enables single-sided printed circuit board layout; (7)High bandwidth provides fast turn on with no overshoot and excellent transient load response; (8)Extended creepage between DRAIN and all other pins improves field reliability.
