5.1 Definitions

This procedure details how to configure the UCC2x5xx evaluation board. Within this test procedure the following naming conventions are followed. Refer to the UCC21520EVM-286 Schematic in Figure 8-1 for details.

    VXXExternal voltage supply name
    V(TPxx)Voltage at test point TPxx. For example, V(TP12) means the voltage at TP12
    V(Jxx)Voltage at jack terminal Jxx
    Jxx(yy)Terminal or pin yy of jack xx
    DMMDigital multi-meters
    UUTUnit under test
    EVMEvaluation module assembly, in this case the UUT assembly drawings have location for jumpers, test points and individual components
