2.1.2.1 Voltage Source

The input voltage source VIN must be a 0V to 18V variable DC source capable of supplying a minimum of 16ADC to support a 50A load with 12V input. Connect input VIN and GND to T1 and T2. If the output voltage of the EVM increases, then the power supply must be capable of supplying more current.
