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 control provides constant efficiency down to very light loads

– ideal for mandatory CEC regulations and EuP standby requirements
