Soldering Guidelines
To avoid damaging the integrated circuit (IC), use a hot-air system for any solder rework to modify the
EVM for the purpose of repair or other application reasons.
2.4
Equipment Connection
Use the following guidelines when connecting the equipment:
1. Set the positive input supply to 33 V (max), and turn the power supply off.
2. Set the negative input supply to –33 V (min), and turn the power supply off.
3. Connect the positive voltage lead from the input power supply to INP at the J8 connector of the EVM.
4. Connect the negative voltage lead from the input power supply to INN at the J10 connector of the
EVM.
5. Connect the ground lead from the input power supply to GND at the J6 and J12 connector of the EVM.
6. Connect a 0 mA to 150 mA load between OUTP and GND.
7. Connect a 0 mA to 150 mA load between OUTN and GND.
8. Disable the output by floating J15.

Operation
Operate the EVM using the following steps:
1. Turn on the power supplies.
2. Enable the output by jumping J15, the EN pin, to VIN.
3. Vary the respective load and input voltage, as necessary, for test purposes.
