TNY177PN (Switch Power IC)
BD 3.000
TinySwitch™-LT incorporates a 650 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.
Applications
• Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.
• DVD/PVR and other low power set top decoders
• Supplies for appliances, industrial systems, metering, etc.
Enhanced Safety and Reliability Features
• Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset
• Auto-restart delivers <3% of maximum power in short-circuit and open loop fault conditions
• Output overvoltage shutdown with optional Zener
• Very low component count enhances reliability and enables single-sided printed circuit board layout
• High bandwidth provides fast turn on with no overshoot and excellent transient load response
• Extended c
