Apply power (48 V) to the TPS9250EVM-133 board (terminal J1). Connect a resistive or a current sink load such
as LEDs or diodes to the output of the EVM (terminal J2). The load should not exceed maximum output current
of 1.6 A and the maximum output power of 120 W for 2-channel operation. The following steps then provide the
