Energy-Effcient, Off-Line Switcher With Line Compensated Overload Power

Power Integrations, Inc 

TNY284-290

TinySwitch™-4 Family

Energy-Efficient, Off-Line Switcher With

Line Compensated Overload Power

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 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 EMII

Enhanced Safety and Reliability Features

• 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

• 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

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.

Notes:

1. Minimum continuous power in a typical non-ventilated enclosed adapter

measured at +50 °C ambient. Use of an external heat sink will increase power

capability.

2. Minimum peak power capability in any design or minimum continuous power in

an open frame design (see Key Applications Considerations).
