    BCM20737 power consumption [using External DCDC down converter(XC9265B1214R-G)]

      Dear Support,

       

      I had measured power  consumption [( BCM20737, Using External DC-DC down converter(XC9265B1214R-G)]

       

      Power consumption is 130uA ( Advertising Interval 2 sec, Average current 2 minute )

      But, BCM920737_LE_TAG4 power consumption is 45uA ( Same condition, Same F/W )

       

      Q1) Why our board is power consumption higher than TAG4?

       

      Q2) Our board's current is changed by Supply Voltage, but TAG4 is not.

             ex) Supply Voltage 3.3V - 100uA, Supply Voltage 3.0V - 35uA, Supply Voltage 2.5V - 22uA.......

       

      The follow picture is our test condition.

      If you want our schematic & PCB file, I will send you by e-mail

       

      Thanks for your support.

      BR.
