#[CC2541 KEYFOB] Current Consumption Reduction

Other Parts Discussed in Thread: CC2541, ASH, TPS62730

Dear TI, As a newbee, I am working with CC2541 and following Keyfob example for reference. I want to reduce the currrent consumption at its maximum level. What are the waus and how I can implement those methods to reduce the current consumption ? I am getting 2000uA at present which is too high for my application, while set the GPIO optimally. Please suggest some valuable ways to reduce the current consumption at its maximum. Thanks, Regards /Ash

    Hi Ash,

    For which state are you getting 2 mA? I hope it is not when the device is in sleep? The peak current consumption will be when the device is in TX and it will be around 20 mA (or 15 mA if you are using TPS62730). The only way to reduce this is to turn down the output power.

    Cheers,
    Fredrik

    Dear Fredrik,Thanks for your reply~
    well, I am getting 2mA during normal mode. Also, I am not using TPS62730, so I want to know how much the minimum and maximum value of the current consumption in the case of Keyfob?
    Also, please suggest me, how can I check whether my device is going in PM2 mode or not (in code) ?
    Thanks a lot~Regards/Ash
