Introduction

AI Translation

TinySwitch™-LT incorporates a 650 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.

Features

AI Translation
  • 650 V rating optimized for non-active PFC applications
  • 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-LT 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 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
  • 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

Applications

AI Translation
  • Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc.
  • DVD/PVR and other low power set top decoders
  • Supplies for appliances, industrial systems, metering, etc.
