3 Test Result

In this application note, the test is performed using the LM5176EVM-HP and MSPM0G3507 Launchpad. Due to the requirement of an adjustable output voltage, R22 is replaced by an 11 kΩ resistor. C13 and C14 are replaced by 330 uF 100 V capacitors on the LM5176EVM-HP; the other components remain the same. The TEC element used in the test is MCTE1-19913L-S (Vmax: 24.1 V, Imax: 13 A).
