TNY284KG Datasheet Text
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
- Simple ON/OFF control, no loop pensation needed
- Selectable current limit through BP/M capacitor value
- Higher current limit extends peak power or, in open frame applications, maximum continuous power
- Lower current limit improves efficiency in enclosed adapters/ chargers
- Allows optimum TinySwitch™-4 choice by swapping devices with no other circuit redesign
- Tight I2f parameter tolerance reduces system cost
- Maximizes MOSFET and magnetics utilization
- ON-time extension
- extends low-line regulation range/hold-up time to reduce input bulk capacitance
- Self-biased: no bias winding or bias ponents
- Frequency jittering reduces EMI filter costs
- Pin-out simplifies heat sinking to the PCB
- SOURCE pins are electrically quiet for low EMI
Enhanced Safety and Reliability 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
- Fast AC reset with optional UV external resistor
- 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...
