SLUUCZ1 July 2024 TPS546C25
The TPS546C25EVM-1PH includes a 10Ω series resistor in the feedback loop for VOUT. The resistor is accessible at test points TP13 and TP5 for loop response analysis. Use these test points during loop response measurements as the perturbation injecting points for the loop. See the description in Table 5-3 on how to connect test equipment.
Test Point | Node Name | Description | Comment |
---|---|---|---|
TP5 | CH2 | Input to feedback divider of VOUT | Limit the amplitude of the perturbation at this node to less than TBDmV |
TP13 | CH1 | Resulting output of VOUT | Bode is measurable by a network analyzer with a CH2/CH1 configuration |
Measure the loop response with the following procedure:
