Introduction

AI Translation

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.

Features

AI Translation
  • Minimum system cost with enhanced flexibility:
    • Simple ON/OFF control — no loop compensation required
    • Selectable current limit via BP/M capacitor value
    • Higher current limit for extended peak power or maximum continuous power in open-frame applications
    • Lower current limit for improved efficiency in enclosed adapter/charger applications
    • Optimal TinySwitch-III selection via device substitution — no redesign of surrounding circuitry required
    • Tight I parameter tolerance for reduced system cost
    • Maximized power delivery through MOSFET and magnetic components
    • Minimized maximum overload power, reducing transformer, primary clamp, and secondary component costs
    • Extended on-time — widened low-line regulation range/hold-up time to reduce input bulk capacitance
    • Self-biased: no bias winding or bias components required
    • Frequency jitter for reduced EMI filter cost
    • Pin layout simplifies PCB thermal management
    • Electrically quiet source pin for reduced EMI
  • Enhanced safety and reliability features:
    • Accurate hysteretic thermal shutdown with auto-recovery — no manual reset required
    • Improved auto-restart providing <3% maximum power under short-circuit and open-loop fault conditions
    • Output overvoltage shutdown with optional Zener diode
    • Line undervoltage detection threshold settable via single optional resistor
    • Ultra-low component count for enhanced reliability and single-sided PCB layout support
    • High bandwidth for fast turn-on with no overshoot and excellent transient load response
    • Extended creepage distance between drain and all other pins for improved field reliability
  • EcoSmart — Extremely High Energy Efficiency:
    • Easily meets all global energy efficiency regulations
    • No-load consumption <150mW at 265 VAC without bias winding; <50mW with bias winding
    • ON/OFF control delivers constant efficiency at light load — ideal for mandatory CEC regulations and 1 W PC standby requirements

Applications

AI Translation
  • 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.
