Figure 47: STEVAL-ISB044V1 evaluation board: efficiency performance with MP1B Rx
The maximum efficiency is 82.2% at 7 W.
5.4
Stand-by consumption
In stand-by, when the board is supplied at 12 V, very low power consumption is achieved.
In this mode, device detection is still ensured; power consumption is reduced down to 1.4
mA average.
The STEVAL-ISB044V1 evaluation board has a low stand-by power of only 17 mW.
To measure this low power consumption, the UART cable must be unplugged.
