The EVM is designed to accommodate different input voltage levels for the power stage and control logic. During normal operation, the PVIN and VIN inputs are connected together using a jumper across J3. The single input voltage is supplied at J1. If desired, these to input voltage rails may be separated by removing the jumper across J3. Two input voltages must then be provided at both J1 and J2.
