When testing the 24 V to 15 V WE-PPTI 1308 part, the closest competitor part was chosen to test alongside. The Würth Elektronik part has 18% less volume than the competitor part while having a significantly lower profile as well. Both parts were tested on the SN6507 EVM available from Texas Instruments with no component changes for the default 1 MHz operation. Both parts were also tested at 400 kHz.
