    Products Detail

    LinkSwitch-TN integrates a 700 V power MOSFET, oscillator, control circuitry, and protection features into a monolithic IC. It replaces linear and capacitor-fed power supplies with higher efficiency and performance. Key features include: lowest component count and cost, fully integrated auto-restart for fault protection, 66 kHz operation with accurate current limit, 700 V breakdown voltage for surge withstand, frequency jittering to reduce EMI (~10 dB), high thermal shutdown temperature (+135 °C minimum), support for buck, buck-boost, and flyback topologies, universal input voltage range (85 VAC to 265 VAC), and EcoSmart energy efficiency with ultra-low no-load consumption (50/80 mW in buck topology).

    Key Features

    • Lowest cost and component count buck converter solution
    • Fully integrated auto-restart for short-circuit and open loop fault protection
    • 66 kHz operation with accurate current limit
    • High breakdown voltage of 700 V
    • Frequency jittering reduces EMI (~10 dB)
    • High thermal shutdown temperature (+135 °C minimum)
    • Supports buck, buck-boost, and flyback topologies
    • System-level thermal overload, output short-circuit, and open control loop protection
    • Universal input voltage range (85 VAC to 265 VAC)
    • Built-in current limit and hysteretic thermal protection
    • EcoSmart energy efficiency
    • Meets CEC, Energy Star, and EU requirements
