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 ca...
