TNY175PN
TNY175PN is Offline Switcher manufactured by Power Integrations.
- Part of the TNY177 comparator family.
- Part of the TNY177 comparator family.
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 ponent 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 creepage between DRAIN and all other pins improves field reliability
Eco Smart™- Extremely Energy Efficient
- Easily meets all global energy efficiency regulations
- No-load <150 m W at 265 VAC without bias winding,
<50 m W with bias winding
- ON/OFF control provides constant efficiency down to very light loads
- ideal for mandatory CEC regulations
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.
Description
Tiny Switch™-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.
