Overview

TinySwitch-4 combines a high-voltage power MOSFET switch with a power supply controller in one device. Unlike conventional PWM (pulse width modulator) controllers, it uses a simple ON/OFF control to regulate the output voltage.

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.

Key features

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 EMI
Accurate hysteretic thermal shutdown protection with automatic 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
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
