SBAU227A March 2014 – June 2021 TPS56520 , TPS56720 , TPS56920 , TPS56C20
The TPS56C20EVM-614 provides input/output connectors and test points as shown in Table 4-1. The design requires a power supply capable of supplying 4 A to connect to J1 through a pair of 20-AWG wires. The design requires the load to connect to J3 through a pair of 20-AWG wires. The maximum load current capability is 12 A. Wire lengths must be minimized to reduce losses in the wires. Test point TP3 provides a place to monitor the VIN input voltages with TP4 (which provides a convenient ground reference). The design uses TP6 to monitor the output voltage with TP7 as the ground reference.
