Overview
TNY284-290 TinySwitch-4 Family Energy-Efficient, Off-Line Switcher with Line Compensated Overload Power Product Highlights Lowest System Cost with Enhanced Flexibility • 725 V rated MOSFET • Increases BV de-rating margin • Line compensated overload power – no additional components • 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 compensation 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 components • 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 component 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 <30 mW with bias winding, <150 mW at 265 VAC without bias winding • ON/OFF c...
