Hi,
I am looking to measure the current consumed by the CPU/MPU of the DM3730, which is supplied by the TPS65950, I am using the Beagleboard-xM (I know there are current measurement pins on the board but they measure the current of the whole board).
Looking at the datasheets/reference manuals:

http://www.ti.com/lit/ds/symlink/tps65950.pdf
Seeing that VDD1 is the power input for the MPU, the current needs to be measured at this point. In my board it is connected to VDD1 of the TPS65950. Based on the Figure 4-1 of the TPS65950, VDD1.L seems to be the output current whereas VDD1.OUT seems to be some sort of input to the TPS65950. The inductor LVDD1 (of 1uH) needs to be connected between VDD1.L and VDD1.
My question is, based on Figure 4-1 where there are arrows coming in and out of VDD1; is VDD1.L supplying the current? (there is an arrow pointing outside of TPS65950) In that case, if I put a probe on LVDD1 can I measure the current being consumed on VDD1?
Regards,
Luis
