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 effciency 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 flter costs

• Pin-out simplifes heat sinking to the PCB

• SOURCE pins are electrically quiet for low EMII

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 feld reliability

EcoSmart™– Extremely Energy Effcient

• Easily meets all global energy effciency regulations

• No-load <30 mW with bias winding, <150 mW at 265 VAC without bias winding

• ON/OFF control provides constant effciency down to very light loads – ideal for mandatory CEC regulations and EuP standby requirements

Applications

• PC Standby and other auxiliary supplies

• DVD/PVR and other low power set top decoders

• Supplies for appliances, industrial systems, metering, etc

• Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.
