    Products Detail

    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. It features enhanced safety and reliability, EcoSmart® energy efficiency, and reduced component count for improved reliability.

    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 maximum continuous power
    • Lower current limit improves efficiency in enclosed adapters/chargers
    • Tight I²f parameter tolerance reduces system cost
    • ON-time extension for low line regulation/hold-up time
    • Self-biased: no bias winding or bias components
    • Frequency jittering reduces EMI filter costs
    • Pin-out simplifies heatsinking
    • SOURCE pins electrically quiet for low EMI
    • Accurate hysteretic thermal shutdown with auto-restart
    • Improved auto-restart delivers <3% max power in faults
    • Output overvoltage shutdown with optional Zener
    • Line undervoltage detect with single resistor
    • Very low component count enhances reliability
    • High bandwidth for fast turn-on with no overshoot
    • Extended creepage between DRAIN and other pins
    • Meets global energy efficiency regulations
    • No-load <150 mW at 265 VAC without bias, <50 mW with bias
    • Constant efficiency down to very light loads

    Application scenarios

    • Chargers/adapters for cell/cordless phones
    • PDAs
    • digital cameras
    • MP3/portable audio
    • shavers; PC Standby and other auxiliary supplies; DVD/PVR and other low power set top decoders; Supplies for appliances
