TNY290 Overview
TNY284-290 TinySwitch-4 Family Energy-Efficient, Off-Line Switcher with Line pensated Overload Power Product Highlights Lowest System Cost with Enhanced Flexibility 725 V rated MOSFET Increases BV de-rating margin Line pensated overload power no additional ponents Dramatically reduces max overload variation over universal input voltage range ±5% turn on UV threshold: line voltage sense with single external resistor...
TNY290 Key Features
- Accurate hysteretic thermal shutdown protection with automatic
- Auto-restart delivers <3% of maximum power in short-circuit and
- Output overvoltage shutdown with optional Zener
- Fast AC reset with optional UV external resistor
- 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 <30 mW with bias winding, <150 mW at 265 VAC without
- ON/OFF control provides constant efficiency down to very light loads
TNY290 Applications
- Lower current limit improves efficiency in enclosed adapters/ chargers
- Allows optimum TinySwitch™-4 choice by swapping devices with no other circuit redesign
