2.6.1 UCC27511 Modification

The UCC57142EVM out-of-the-box can be made compatible with the UCC27511 through the following modifications:

  1. Remove any jumpers present on the EVM.
  2. Remove R1, R3, R7, and D1.
  3. Short C4, and C5.
  4. Populate R5 with gate resistor.
  5. Replace C7 with a 1μF capacitor (VDD bypass capacitor).

Table 2-5 lists how the I/O headers are used for the UCC27511.

Table 2-5 Header Functionality

EVM Header

Function

OCP / OCP_IN

VDD pin / VCC signal input

GND_IO

OUTH pin

OUT / Gate

OUTL pin / Gate

VDD / VCC

GND pin / unused

EN/FLT / EN/FLT_IN

 IN- pin / IN- signal input(1)

IN / IN_IN

 IN+ pin / IN+ signal input(1)
(1) The UCC27511 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.
