2.6.2 UCC27517 and UC27533 Modification

The UCC57142EVM out-of-the-box can be made compatible with the UCC27517 and UCC27533 through the following modifications:

  1. Remove any jumpers present on the EVM.
  2. Remove R1, D1, C3, and C4.
  3. Short R11.
  4. Adjust C8 to your desired load value.
  5. Adjust R6 to your desired gate resistance.
  6. Replace C7 with a 1μF capacitor (VDD bypass capacitor).

Table 2-6 lists how the I/O headers will be used for the UCC27517 and UCC27533.

Table 2-6 Header Functionality
EVM Header Function
OCP / OCP_IN VDD pin / VDD signal input
GND_IO GND pin
OUT / Gate IN+ pin / IN+ signal input(1)
VDD / VCC IN- pin / IN- signal input(1)
EN/FLT / EN/FLT_IN Unused
IN / IN_IN OUT pin / Gate
(1) The UCC27517 requires the input pins to be biased for proper operation. If using the driver in non-inverting configuration, then bias IN- pin to GND. If using the driver in inverting configuration, then bias IN+ pin to VDD. Bias the pins using the appropiate headers.
