I have two TPSM41625MOVR devices in stacked mode - a Primary and Secondary. I am fortunate enough to have a thermal camera to observe the two units. ( - And make sure I don't burn myself. ) The primary operates at about 58*C, the secondary at 50*C. The load is 0.90V at 25 Amps. Would this temperature differential be considered normal. I feel if both units are sharing the load they should be approximately the same temperature. How can I tell if the secondary unit is really operating properly?
I understand there may be reasons they would be different - but there is no noticeable difference in the layout of the two units. I expect few degrees, but not 8.
