Page 11: Evaluation With The Tps6204Xevm
Chapter 2 Evaluation With the TPS6204xEVM This chapter details the evaluation process and features of the EVM. For this purpose, a load is connected to the output pins V and GND, which allows the load current to be adjusted between 0 A and 1.2 A. For accurate output voltage and input voltage measurements, it is important to measure the voltage on the input and output voltage terminals with a voltmeter connected directly to the input voltage or output voltage terminals. -
