The TPSM8286xAA0xEVM was used to take all the data in the TPSM8286x 4-A and 6-A High Efficiency Step-Down Converter QFN Power Module data sheet. See the device data sheet for the performance of this EVM.

Figure 4-1 shows the thermal performance of the TPSM82866AA0SEVM and Figure 4-2 shows the thermal performance of the TPSM82866AA0HEVM. Figure 4-3 shows the loop response measurement of all EVMs.
