Is it ok doubler circuit for powering nRF52832 custom board

vishal

Hello Everyone,

I have developed my application using BLE for connect android mobile. I have design complete PCB using your reference design. But i have littele confused in power supply schematic because i have use MCP1640 doubler IC, and use only one AA 1.5V battery and converted to 3.3V. my question is i have this attached schematic to powering Nordic chip. Is it sufficient for continuously power to nRF52832 or i need to add any other components with this circuit. I just verify this circuit and hope it will not cause problem in future. I have tested this circuit in general purpose PCB its working fine and that's why i am using in my final design. Any extra energy consumption due this doubler circuit my device current consumption is 4mA-6mA. Please give your valuable suggestion for should i use thisimage description.

    Hi Sir, Finally we again decide to use momentary switch in my device so now as per my previous question i added circuit diagram here Please sir see again as per your suggestion for use high value resistor i have few question on same following:

    1. If i use 10K for protecting internal diode in nRF52832 SoC is it Ok, then by adding this resistor will be consume more current or this will not affect on current consumption.
    2. Also my confusion is if instead of resistor i use diode for protection reverse voltage at the time of user press switch is it work for long time, or it will consume more current or not due to use diode.

    Please sir let me know the above question asap, now we are in final stage design. Thanks.....
