2.6.4 UCC44273 Modification

The UCC57142EVM out-the-box can be made compatible with the UCC44273 through the following modifications:

  1. Remove any jumpers present on the EVM.
  2. Remove R3, R6, C4, and C5.
  3. Short R2.
  4. Populate C6 with a 1μF capacitor (VDD bypass capacitor).

Table 2-9 lists how the I/O headers will be used for the UCC44273.
