TNY174P Datasheet | Power Integrations

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. AC Input D EN Tiny Switch-LT BP/M Figure 1.
