5.2 External Connections for Easy Evaluation

The UCC12050EVM-022 EVM utilizes screw terminals for quickly connecting to VINP and VISO. Connect a +5 V supply (+4.5 V to +5.5 V) between VINP and GNDP of J1 to supply power to the board. Connect a variable load between VISO and GNDS of J6. Alternatively, R4 is available to solder down a load resistor directly to the board. It is recommended to use an 0805 resistor that is rated for 0.5 W or greater. The value depends on the application needs, but the load should not exceed 0.5 W.
