Page 3: Description
Description 1 Description The TPSM8D6C24 is a configurable dual-output buck converter module. The TPSM8D6C24EVM-2V0 uses a nominal 12-V bus to produce a regulated 0.8-V and 1.2-V output at up to 35 A of load current each. The TPSM8D6C24EVM-2V0 demonstrates the dual output capability. -

Page 10: Control Loop Gain And Phase Measurement Procedure
VOUT– (GND) 6.3 Control Loop Gain and Phase Measurement Procedure The TPSM8D6C24EVM-2V0 includes a 49.9-Ω series resistor in the feedback loop for V . The resistor is accessible at the test points TP7, TP8, TP19, and TP20 for loop response analysis. These test points should be used during loop response measurements as the perturbation injecting points for the loop. -
