    Single 1A, 1.4 MHz Synchronous Buck Regulator
    Features Description The MCP1612 is a 1A, 1.4 MHz, fully-integrated,
    current mode-controlled, synchronous buck regulator.
    The MCP1612 is packaged in the 8-pin MSOP and
    space-saving, 3x3 DFN packages. The DFN package
    also provides a lower thermal resistance package
    option for high-power, high ambient temperature
    applications. With an input operating range from 2.7V
    to 5.5V, the MCP1612 is ideal for applications that are
    powered by one single-cell Li-Ion, 2-to 3-cell NiMH,
    NiCd or alkaline sources. Fixed Switching Frequency: 1.4 MHz
    Input Operating Voltage Range: 2.7V to 5.5V
    Integrated Buck and Synchronous Switches
    Adjustable-Output Voltage Range: 0.8V to 5.0V
    100% Duty Cycle Capable for Low Input Voltage
    Continuous Output Current Capability: 1A
    Shutdown Control with IQ < 0.01 ВµA (Typ.)
    Integrated Soft-Start Feature
    Integrated Undervoltage Lockout (UVLO)
    Integrated Overtemperature Protection
    Fast Dynamic Response to Line and Load Steps ...
