Battery step up circuit converter using MCP1640

This battery step up circuit converter is designed using MCP1640 integrated circuit specially designed for applications powered by batteries ( NiCd, NiMH, one-cell Li-Ion or Li-Polymer).
The MCP1640 battery step up circuit converter is designed with low-voltage technology that allows the regulator to start up without high inrush current or output voltage overshoot from a low 0.65V input.
The MCP1640 can provide the following output current :
- 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
The output voltage provided by the circuit can be adjusted between 2 and 5.5 volts.
This DC converter can be used for powering portable devices like: personal medical products, wireless sensors, handheld instruments, GPS receivers, bluetooth headsets, etc.
