    400 mA nano-quiescent synchronous step-down converter with digital voltage selection and Power Good

    Parameters
    Input Voltage Min Volt0.625
    Input Voltage Max Volt5.5
    ECCN USEAR99
    ECCN EUNEC
    Packing TypeTape And Reel
    RoHs compliantEcopack2
    GradeIndustrial
    Package NameCSP P 0.4 mm
    Description

    This converter is specifically designed for applications where high efficiency, PCB size and thickness are the key factors. The output voltage can be set using two digital control inputs, a VOUT from 0.625 V to 3.3 V can be dynamically selected. Thanks to the enhanced PCC (peak current control) the...
