    Products Detail

    The LinkSwitch-HP family monolithically integrates a controller and high-voltage power MOSFET into one package. It uses an enhanced peak current mode PWM control scheme with multi-mode operation to enable continuous conduction mode (CCM) primary side regulated (PSR) power supplies up to 90 W without the efficiency limitation of DCM or audible noise. The multi-mode control engine maintains output voltage regulation by adjusting operating current and switching frequency based on the error amplifier output. It eliminates the need for optocouplers and secondary control circuitry, dramatically simplifying power supply designs while providing ±5% output voltage tolerance.

    Key Features

    • Multi-mode control maximizes efficiency over full load range
    • No-load consumption below 30 mW at 230 VAC (LNK67xx)
    • >75% efficiency with 1 W input at 230 VAC
    • >50% efficiency with 0.1 W input at 230 VAC
    • Eliminates optocoupler and all secondary control circuitry
    • ±5% or better output voltage tolerance
    • 132 kHz operation reduces transformer and power supply size
    • Accurate programmable current limit
    • Compensation over line limits overload power
    • Frequency jittering reduces EMI filter cost
    • Fully integrated soft-start for minimum start-up stress
    • 725 V MOSFET (LNK677x) or 650 V MOSFET (LNK676x/LNK666x)
    • Fast transient response family option (LNK666x)
    • Extensive protection features including auto-restart, SCP, OPP, OCP, OVP, line UV/OV, OTP
    • Advanced green package options (eSIP-7C, eSOP-12B, eDIP-12B)
    • Halogen free and RoHS compliant

    Application scenarios

    • LCD Monitor and TV
    • Adapter
    • Appliances
    • Embedded power supplies (DVD, set-top box)
