TNY175
Description
TinySwitch™-LT incorporates a 650 V power MOSFET, oscillator, high-voltage switched current source, current limit (user selectable) and thermal shutdown circuitry.
Key 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 EcoSmart™- Extremely Energy Efficient
- Easily meets all global energy efficiency regulations
- No-load <150 mW at 265 VAC without bias winding, <50 mW with bias winding
- ON/OFF control provides constant efficiency down to very light loads
- ideal for mandatory CEC regulations
Applications
- Lower current limit improves efficiency in enclosed adapters/
