Product Descriptions

TinySwitch?-III incorporates a 700 V power MOSFET, oscillator, high-voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability.

Product Features

Lowest System Cost with Enhanced Flexibility

? 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-III choice by swapping devices with no other circuit redesign

? Tight I2f 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 filter costs

? Pin-out simplifies 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

? Improved auto-restart delivers <3 percent of maximum power in short-circuit and open loop fault conditions

? Output overvoltage shutdown with optional Zener

? Line undervoltage detect threshold set using a single optional resistor

? Very low component count enhances reliability and enablessingle-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 <150 mW at 265 VAC without bias winding, <50 mW with bias winding

? ON/OFF control provides constant efficiency down to very light loads – ideal for mandatory CEC regulations and 1 W PC standby requirements

Product Applications

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

? PC Standby and other auxiliary supplies

? DVD/PVR and other low power set top decoders

? Supplies for appliances, industrial systems, metering, etc.
