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.
