Setup
1. Configure the specified test equipment as shown in Figure 2, where Jumper 1 placement options are illustrated.
2. An additional 100μF or greater capacitor [C_ADD in Figure 2] may be required to decouple the input power supply and
maintain stable operation. Solder the additional capacitor to the VIN and GND terminals on the AAT1299 evaluation
board.
3. An input power supply with remote sense may be used. This simplifies the test procedure and maintains high
accuracy of the input voltage across the loading range. Connect the input power source remote sense terminals to
the VIN and GND terminals on the AAT1299 evaluation board (optional, not shown in Figure 2).
