The load switches can be connected to the BUCK regulators and two respective loads on the Evaluation Kit (EK).
The load switch inputs are connected to VOUT1 and VOUT2 with jumpers on P15. The load switch outputs are connected to a low-current and a high-current load.

The following table show options for configuring the load switch inputs and outputs.
| Configuration | PMIC pin | Connected net | Connecting jumper pins | Comment |
|---|---|---|---|---|
| Load switch input | LSIN1 | VOUT1 | P15 pin 1 to pin 2 | Load switch source is BUCK1 |
| LSIN2 | VOUT2 | P15 pin 3 to pin 4 | Load switch source is BUCK2 | |
| Load switch output | LSOUT1 | R8 | P15 pin 5 to pin 6 | High-current load, 34.8 Ω |
| LSOUT2 | R7 | P15 pin 7 to pin 8 | Low-current load, 18.0 kΩ |
