Lowest System Cost with Enhanced Flexibility
• 650 V rating optimized for non-active PFC applications
• 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 effi ciency in enclosed
adapters/chargers
– Allows optimum TinySwitch-LT choice by swapping
devices with no other circuit redesign
• Tight I2
f parameter tolerance reduces system cost
– Maximizes MOSFET and magnetics power delivery
– Minimizes max overload power, reducing cost of
transformer, primary clamp & secondary components
• 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 fi lter costs
• Pin-out simplifi es heatsinking 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 circuit and open loop fault conditions
• Output overvoltage shutdown with optional Zener
• 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 fi eld reliability
EcoSmart®
– Extremely Energy Effi cient
• Easily meets all global energy effi ciency regulations
• No-load • ON/OFF control provides constant effi ciency down to
very light loads – ideal for mandatory CEC regulations
Applications
• Chargers/adapters for cell/cordless phones, PDAs, digital
cameras, MP3/portable audio, shavers, etc.
• DVD/PVR and other low power set top decoders
• Supplies for appliances, industrial systems, metering, etc.
