    Integrated Synchronous Switch Step-Down Regulator
    Features General Description The MCP16311/2 is a compact, high-efficiency, fixed
    frequency, synchronous step-down DC-DC converter in
    an 8-pin MSOP, or 2 x 3 TDFN package that operates
    from input voltage sources up to 30V. Integrated
    features include a high-side and a low-side switch, fixed
    frequency peak current mode control, internal
    compensation, peak current limit and overtemperature
    protection. The MCP16311/2 provides all the active
    functions for local DC-DC conversion, with fast transient
    response and accurate regulation. Up to 95% Efficiency
