2.2 Setup

To operate the EVM, only one switch per CFG pin must be turned ON. The switch-blocks pair S1 and S4 is connected to CFG1, the pair S2 and S5 is connected to CFG2, and the pair S3 and S6 is connected to CFG3. Table 2-1 and Table 2-2 define the switches to be turned ON corresponding to the desired output voltage and current limit. Make sure exactly one switch per switch-block pair is set to ON. Connect an input supply with the positive lead to J1, pins 1 and 2, and negative lead to J1, pins 5 and 6. Connect a load with the positive lead to J2, pins 1 and 2, and the negative lead to J2, pins 5 and 6. Short EN and ON (pins 2 and 3) of JP2 with a shorting jumper.
