1 Evaluation Module Overview 1.1 Introduction The TPS544C27EVM is a configurable single output buck converter module. The TPS544C27EVM uses a nominal 12V bus to produce a regulated 1V output up to 35A of load current. This user's guide describes the characteristics, operation and using of TPS544C27EVM.
TPS544C27 device in a buck design. TPS544C27 is designed from a nominal 12V bus to produce a regulated 1V output up to 35A of load current. The TPS544C27EVM provides a number of test points to evaluate the performance of device.

Output J3(1V output) – The minimum recommended wire size is AWG #10, with the total length of wire less than 2 feet (1 foot output, 1 foot return). A thicker wire gauge can be required to minimize the voltage drop the wires. TPS544C27EVM 4V to 18V, 35A Step-Down Converter Evaluation Module SLUUCU5 – JUNE 2024 Submit Document Feedback...

VOUT– (GND) 2.4 Control Loop Gain and Phase Measurement The TPS544C27EVM includes a R7 10Ω series resistor in the feedback loop for V . The resistor is accessible at the test points TP14 (BODE_CHA) and TP8 (VOUT/BODE_CHB) for loop response analysis. These test points must be used during loop response measurements as the perturbation injecting points for the loop .

EN signal goes high. 2.6 Input Current Measurement TPS544C27EVM default setting is that input current measurement feature is not used with IN_IN_P and I_IN_M shorted together then shorts to PVIN through J16 shunt on. To test I_IN_P and I_IN_M feature, remove the shunt from J16, connect pin1 of J2 (IIN) to pin2 of J1 (PVIN) with a short 10-AWG wires or better.
