    Choose 4.5V to 50V Input Voltage Single-Supply Operation Power Good (PG) Output Low Radiated Emission (EMI) per EN55022, Class B Adjustable Current Limit Adjustable Output Voltage from 0.9V to 24V (Also
    Limited by Duty Cycle) 200 kHz to 600 kHz, Programmable Switching
    Frequency Supports Safe Start-Up into a Prebiased Output –40°C to +125°C Junction Temperature Range Available in 64-pin, 12 mm × 12 mm × 3 mm QFN
    Package MIC28303 is synchronous step-down regulator
    module, featuring a unique adaptive ON-time control
    architecture. The module incorporates a DC/DC
    controller, power MOSFETs, bootstrap diode, bootstrap
    capacitor and an inductor in a single package. The
    MIC28303 operates over an input supply range from
    4.5V-50V and can be used to supply up to 3A of output
    current. The output voltage is adjustable down to 0.8V
    with an accuracy of ±1%. The device operates with
    programmable switching frequency from 200 kHz-600
    The MIC28303-1 uses HyperLight Load® architecture
    for improved efficiency at light loads. The MIC28303-2
    uses Hyper Speed Control® for ultra-fast transient ...
