    n Frequency Synchronizatio Output Overvoltage Protectio Output Overcurrent Foldback Protectio 9mm × 15mm × 3.51mm BGA Package The LTM®4645 is a 25A output switching mode step-down
    DC/DC µModule® (power module) regulator. Included in
    the package are the switching controller, power FETs, inductor and all supporting components. Operating over an
    input voltage range of 4.7V to 15V, the LTM4645 supports
    an output voltage range of 0.6V to 1.8V, set by a single
    external resistor. Only a few input and output capacitors
    are needed. n Its high efficiency design delivers about 86% efficiency
    from 12V input to 1.0V output with 25A continuous load
    current. High switching frequency and a current-mode
    architecture enable a very fast transient response to line ...
