Shall i use Doubler circuit using MCP1640 with single AA battery power supply for nRF52832?

vishal

Hello Sir,

I have developed small and compact product using nRF52832 Soc. Due to size limitation and device is portable. I have attached snap shot of power supply circuit as per this circuit this switch is use only for ON device and after some period device will completely shut down not in sleep mode it achieve by MCP1640 EN pin = 0.

This doubler IC EN pin is control in nordic program by define on GPIO pin when momentary switch press EN high and nRF52832 chip ON and then quickly logic high is provide to MCP1640 EN pin in program. After some specified period it will automatically go to shut down by EN= GND. This logic we are using for power save to improve battery life. For controlling enable pin i am using n Channel Power MOSFET with very low VGSth.image description So sir please give me suggestion can i use this type of power source.
