    High-Voltage Input Integrated Switch Step-Down Regulator
    Features General Description The MCP16331 is a highly integrated, high-efficiency,
    fixed frequency, step-down DC-DC converter in a popular
    6-pin SOT-23 or 8-pin 2x3 TDFN package that operates
    from input voltage sources up to 50V. Integrated features
    include a high-side switch, fixed frequency Peak CurrentMode control, internal compensation, peak current limit
    and overtemperature protection. Minimal external components are necessary to develop a complete step-down
    DC-DC converter power supply.
    High converter efficiency is achieved by integrating the
    current-limited, low-resistance, high-speed N-Channel
    MOSFET and associated drive circuitry. High switching
    frequency minimizes the size of external filtering
    components, resulting in a small solution size.
    The MCP16331 can supply 500 mA of continuous
    current while regulating the output voltage from 2.0V to
    24V. An integrated, high-performance Peak CurrentMode architecture keeps the output voltage tightly regulated, even during input voltage steps and output current
    transient conditions that are common in power systems.
    The EN input is used to turn the device on and off.
    While off, only a few ВµA of current are consumed from
    the input for power shedding and load distribution
    applications. This pin is internally pulled up, so the
    device will start, even if the EN pin is left floating. ...
