5.3.5 Jumper (Shunt) Settings

There are two jumpers (shunts) need to be installed before test:

  1. Install shunt #1 for header J3-DIS on pin EN/DIS-GND for the UCC21520EVM shown in Figure 5-1. For the UCC20520EVM, UCC21521CEVM and the UCC21530EVM, refer to Table 3-1. The UCC20520EVM is set as disable high on the DIS pin while the UCC21521CEM and UCC21530EVM is set as enable high on the EN pin.
  2. Install shunt #2 on header J4-DT on pin VCCI-DT as shown in Figure 5-1.
