    n APPLICATIONS General Purpose Multichannel Power Supplies:
    Automotive, Industrial, Distributed Power Systems n The LTCВ®3371 is a highly flexible multioutput power supply
    IC. The device includes four synchronous buck converters, configured to share eight 1A power stages, each of
    which is powered from independent 2.25V to 5.5V inputs.
    The DC/DCs are assigned to one of eight possible power
    configurations via pin programmable C1-C3 pins. The ...
