TinySwitch-4 Family
Energy-Efficient, Off-Line Switcher With
Line Compensated Overload Power
Product Highlights
Lowest System Cost with Enhanced Flexibility
Enhanced Safety and Reliability Features
EcoSmart
Applications
www.powerint.com
725 V rated MOSFET
Line compensated overload power – no additional components
±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
Tight I
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 EMII
Accurate hysteretic thermal shutdown protection with auto-
matic 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
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
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
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.
Increases BV de-rating margin
Dramatically reduces max overload variation over universal
input voltage range
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
Maximizes MOSFET and magnetics utilization
Fast AC reset with optional UV external resistor

f parameter tolerance reduces system cost
