3.2 Soldering Guidelines
To avoid damaging the integrated circuit (IC), use a hot-air system for any solder rework to modify the
EVM for repair or other application reasons.
3.3 Equipment Connection
1. Set the input power supply to 3.3 V (maximum) and turn the power supply off.
2. Set the bias power supply to 5.5 V (maximum) and turn the power supply off.
3. Connect the positive voltage lead from the input power supply to IN at the J5 connector of the EVM.
4. Connect the ground lead from the input power supply to GND at the J10 connector of the EVM.
5. Connect the positive voltage lead from the bias power supply to BIAS at the J3 connector of the EVM.
6. Connect the ground lead from the bias power supply to GND at the J1 connector of the EVM.
7. Connect a 0-A to 300-mA load between OUT and GND.
8. Float J9 and short J12 to disable the output.
4 Operation
1. Turn on the power supplies.
2. Short J9 (the EN pin) to IN or BIAS and float J12 to enable the output.
3. Vary the respective load and input voltage for test purposes if necessary.
