  • The L6564H is a current-mode PFC controller operating in transition mode (TM) which embeds the same features existing in the L6564 with the addition of a high voltage startup source. These functions make the IC especially suitable for applications that must be compliant with energy saving regulations and where the PFC preregulator works as the master stage.

    The highly linear multiplier, along with a special correction circuit that reduces crossover distortion of the mains current, allows wide-range-mains operation with an extremely low THD even over a large load range.
    The output voltage is controlled by means of a voltage-mode error amplifier and an accurate (1% @TJ= 25 °C) internal voltage reference. The loop stability is optimized by the voltage feedforward function (1/V2 correction), which, in this IC, uses a proprietary technique that also considerably improves line transient response in the case of both mains drops and surges (“bi-directional”).
    In addition to overvoltage protection able to control the output voltage during transient conditions, the IC also provides protection against feedback loop failures or erroneous settings. Other onboard protection functions allow brownout conditions and boost inductor saturation to be safely handled.
    The totem pole output stage, capable of a 600 mA source and 800 mA sink current, is suitable for a high power MOSFET or IGBT drive. This, combined with the other features and the possibility to operate with ST's proprietary fixed-off-time control, makes the device an excellent solution for SMPS up to 400 W that requires compliance with EN61000-3-2 and JEITA-MITI standards.

    Key Features

    • Onboard 700 V startup source
    • Fast “bi-directional” input voltage feedforward (1/V2correction)
    • Accurate adjustable output overvoltage protection
    • Protection against feedback loop disconnection (latched shutdown)
    • Inductor saturation protection
    • AC brownout detection
    • Low (≤ 100 μA) startup current
    • 6 mA max. operating bias current
    • 1% (@ TJ= 25 °C) internal reference voltage
    • -600/+800 mA totem pole gate driver with active pull-down during UVLO
    • SO-14 package
