Application Notes:
The MCP1640/40B/40C/40D 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 one-cell, two-cell, or three-cell alkaline, NiCd, NiMH, one-cell Li-Ion or Li-Polymer batteries. The MCP1640/40B/40C/40D provides very high efficiency through integration of the low resistance N-Channel Boost switch and synchronous P-Channel switch.

- IOUT > 100 mA @ 1.2V VIN, 3.3V VOUT
- IOUT > 350 mA @ 2.4V VIN, 3.3V VOUT
- IOUT > 350 mA @ 3.3V VIN, 5.0V VOUT
- Low Start-up Voltage: 0.65V
- Operating Input Voltage: 0.35V
- Adjustable Output Voltage Range: 2.0V to 5.5V
- Maximum Input Voltage < VOUT < 5.5V
- Automatic PFM/PWM Operation
- PWM Operation at 500 kHz
- Low Device Quiescent Current: 19 µA – typical PFM Mode
- Shutdown Current (All States): < 1 µA
- Internal Synchronous Rectifier
- Internal Compensation
- Inrush Current Limiting and Internal Soft-Start
- True Load Disconnect Shutdown
- Low Noise, Anti-Ringing Control
