Overview

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.

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.

Key features

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
Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset
Improved auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions
Output overvoltage shutdown with optional Zener
Line under-voltage detect threshold set using a single optional 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
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
