TNY178 Description
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. AC Input D TinySwitch-LT S EN BP/M Figure.
TNY178 Key Features
- Auto-restart delivers <3% of maximum power in short-circuit and
- Output overvoltage shutdown with optional Zener
- Very low ponent count enhances reliability and enables
- High bandwidth provides fast turn on with no overshoot and
- Extended creepage between DRAIN and all other pins improves field
- Easily meets all global energy efficiency regulations
- No-load <150 mW at 265 VAC without bias winding
- ON/OFF control provides constant efficiency down to very light loads
- ideal for mandatory CEC regulations
