    MCP1623/24
    Low-Voltage Input Boost Regulator
    for PIC® Microcontrollers
    Features General Description Up to 96% Typical Efficiency 425 mA Typical Peak Input Current Limit:
    -IOUT > 50 mA @ 1.2V VIN, 3.3V VOUT
    -IOUT > 175 mA @ 2.4V VIN, 3.3V VOUT
    -IOUT > 175 mA @ 3.3V VIN, 5.0V VOUT Low Start-Up Voltage: 0.65V, 3.3V VOUT @ 1 mA
    (typical) Low Operating Input Voltage: 0.35V, typical
    3.3VOUT @ 1 mA Adjustable Output Voltage Range: 2.0V to 5.5V Maximum Input Voltage  VOUT < 5.5V Automatic PFM/PWM Operation (MCP1624) PWM-Only Operation (MCP1623) PWM Operation: 500 kHz Low Device Quiescent Current: 19 µA, typical
    PFM Mode Internal Synchronous Rectifier Internal Compensation Inrush Current Limiting and Internal Soft Start True Load Disconnect Shutdown Current (All States): <1 µA Low Noise, Anti-Ringing Control Overtemperature Protection Available Packages:
    -6-Lead SOT-23
    -8-Lead 2 x 3 DFN The MCP1623/24 is a compact, high-efficiency,
    fixed-frequency,
    synchronous
    step-up
    DC-DC
    converter. It provides an easy-to-use power supply
    solution for PIC® microcontroller applications powered
    by either single-cell, two-cell, or three-cell alkaline,
    NiCd, NiMH, and single-cell Li-Ion or Li-Polymer
    batteries. Applications One, Two and Three-Cell Alkaline and NiMH/NiCd
    Low-Power PIC® Microcontroller Applications Low-voltage technology allows the regulator to start up
    without high inrush current or output voltage overshoot ...
