I setup Placid_HD_BP to supply Legato 3.1 with 380mA of current. I measure it accross TP_VIN+ and TP_CCS+ for positive rail.
How can I checked, how many current had been shunted away? At wich pins?
Between TP_OUT+ and TP_SHUNT+ I measured 210mA.
thank you

copied from manual!:
To measure the current being shunted measure the voltage between TP-OUT and TP-SHUNT.

Thank you for the reply.
I wasn't sure if this are the right measuring points.
I set the current accros TP_VIN and TP_CCS to 380mA on both rails.
In this situation I measure 180mA accross TP_SHUNT and TP_OUT
on one rail, on the other it was 205mA.
What could be the cause for different shunting current?
Are this nummbers on the safe side, because the temp. of heatsink is
around 63deg?
regards
