Part Number: TX-SDK-V1 From the Evaluation Kit Users Guide of TX-SDK-V1 the power up sequence that should be followed is: VSUB, +3.3V, +1.8V, ±5V and finally ±10V and ±50V (power down in reverse order). I have a question related to that power sequence: that sequence should be strictly followed (1) or is enough to power on first VSUB and the other power sources in arbitrary form (2)? (if sequence (2) were used, in power down we only have to worry that VSUB in last to power down). I think that the problem in power up/down is related only to VSUB (I am not sure about that!) and as I am now involved in power supply project (I will not follow the the suggested schematic), for me were easy to implement the sequence (2), than sequence (1). I appreciate help in this matter.
