Power consumption in sleep mode

[rajAsthana]

Hi,

I am using NRF52810 controller, The power consumption of my board in SLEEP MODE is 200uA. According to datasheet the ideal current in sleep mode is 3 uA.

In advertising mode the power consumption of my board is 2.25mA. According power profiler https://devzone.nordicsemi.com/nordic/power/w/opp/2/online-power-profiler-for-ble the current consumption is around 40uA.

For reference the advertising parameters and snapshot of nrf Power profiler is given below

Controller  - NRF52810

Clock Source - 32KHz LF External crystal oscillator.

Advertising interval - 300ms

Tx Power set - 0 dBm

Kindly suggest how to achieve current consumption according to NRF power profiler.

Thanks

Raj.

Hi, please provide more information about:

• Software
  • SDK version
  • Based on which example code
  • Any changes to the original code
  • Peripherals used
• Hardware
  • Custom board or DK
  • Post schematic if possible
  • DK version and PCA number
• Measurement setup
  • Equipment used
  • Measurement method: Ampere meter, SMU, etc
  • Wiring
• Plots from measurements showing the high current consumption

Also I would suggest trying the ble_app_pwr_profiling application in the SDK, this starts out in system OFF mode and should give a good indication of measurement errors or other leakage currents on the board.

Thanks
