    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 combines a high-voltage power MOSFET switch with a power supply controller in one device, using simple ON/OFF control to regulate the output voltage.

    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 in open frame applications
    • Lower current limit improves efficiency in enclosed adapters/chargers
    • Allows optimum TinySwitch-III 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 heatsinking to the PCB
    • SOURCE pins are electrically quiet for low EMI
    • Accurate hysteretic thermal shutdown protection with automatic recovery
    • Improved auto-restart delivers <3% of maximum power in short-circuit and open loop fault conditions
    • Output overvoltage shutdown with optional Zener
    • Line undervoltage detect threshold set using a single optional 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
    • EcoSmart™– Extremely Energy Efficient: 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
