connected to the “input” side of a 10 m 1% Kelvin resistor. The “output” side of the
resistor feeds the 2.5V V
Each ML550 voltage regulator output is connected to P72 to permit power plane current
measurements, which can in turn be used in power consumption calculations, recalling
that Power (P) = Voltage (V) x Current (I), and that in the case of the current sense resistor,
Current (I) = Sensed Voltage (V
The ML550 +5V input is also connected through a current measurement resistor. The value
of the resistor (R201) is 5 m . When measuring current using the +5V signals at P72,
