Hej all,
I am planning to use MCP1640 battery boost regulator as power supply to PIC18F2420. My project is about to control 10K-Thermistor sensor. Reading ADC in active mode then go to sleep mode for a while using Timer1 and watch dog timer. I used IC power supply lm7805 but this is not suitable for 3 volt battery supply. The idea for my project is that MCP1640 can supply 3.3 Volt @ output current < 130mA so my question is it a good idea to use MCP1640 with PIC18F2420 to drive 3Volt AAAA battery? Or any one has done it?
