    -IOUT > 350 mA @ 2.4V VIN, 3.3V VOUT
    -IOUT > 350 mA @ 3.3V VIN, 5.0V VOUT Low Start-Up Voltage: 0.65V, typical 3.3V VOUT
    @ 1 mA Low Operating Input Voltage: 0.35V, typical
    3.3VOUT @ 1 mA Adjustable Output Voltage Range: 2.0V to 5.5V Maximum Input Voltage п‚Ј VOUT < 5.5V Automatic PFM/PWM Operation (MCP1640/C):
    -PFM Operation Disabled (MCP1640B/D)
    -PWM Operation: 500 kHz Low Device Quiescent Current: 19 ВµA, typical
    PFM Mode (not switching) Internal Synchronous Rectifier Internal Compensation Inrush Current Limiting and Internal Soft Start Selectable, Logic Controlled Shutdown States:
    -True Load Disconnect Option (MCP1640/B)
    -Input to Output Bypass Option (MCP1640C/D) Shutdown Current (All States): < 1 ВµA Low Noise, Anti-Ringing Control Overtemperature Protection Available Packages:
    -6-Lead SOT-23
    -8-Lead 2 x 3 mm DFN The MCP1640/B/C/D is a compact, high-efficiency,
    fixed frequency, synchronous step-up DC-DC converter. It provides an easy-to-use power supply solution
    for applications powered by either single-cell, two-cell,
    or three-cell alkaline, NiCd, NiMH, and single-cell Li-Ion
    or Li-Polymer batteries.
    Low-voltage technology allows the regulator to start-up
    without high inrush current or output voltage overshoot
    from a low 0.65V input. High efficiency is accomplished ...
