Enhanced Safety and Reliability Features

andbull; Accurate hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset

andbull; Improved auto-restart delivers andlt;3% of maximum power in short-circuit and open loop fault conditions

andbull; Output overvoltage shutdown with optional Zener

andbull; Line undervoltage detect threshold set using a single optional resistor

andbull; Very low component count enhances reliability and enables single-sided printed circuit board layout

andbull; High bandwidth provides fast turn on with no overshoot and excellent transient load response

andbull; Extended creepage between DRAIN and all other pins improves f ield reliability

andnbsp;

Lowest System Cost with Enhanced Flexibility

andbull; Simple ON/OFF control, no loop compensation needed

andbull; Selectable current limit through BP/M capacitor value

andbull; Higher current limit extends peak power or, in open frame applications, maximum continuous power

andbull; Lower current limit improves efficiency in enclosed adapters/chargers

andbull; Allows optimum TinySwitch-III choice by swapping devices with no other circuit redesign

andbull; Tight I2f parameter tolerance reduces system cost

andbull; Maximizes MOSFET and magnetics power delivery

andbull; Minimizes max overload power, reducing cost of transformer, primary clamp andamp; secondary components

andbull; ON-time extension andndash; extends low line regulation range/hold-up time to reduce input bulk capacitance

andbull; Self-biased: no bias winding or bias components

andbull; Frequency jittering reduces EMI filter costs

andbull; Pin-out simplifies heatsinking to the PCB

andbull; SOURCE pins are electrically quiet for low EMI

andnbsp;

Applications

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

andbull; PC Standby and other auxiliary supplies

andbull; DVD/PVR and other low power set top decoders

andbull; Supplies for appliances, industrial systems, metering, etc.
