5.2 Start-Up Procedure

1. Ensure that the jumper at J2 (Enable control) pins 1 and 2 are covered to shunt EN to GND, disabling the output.

2. Apply appropriate VIN voltage to VIN (J1-1) and GND (J1-2).

3. Move the jumper at J2 (Enable control) away from pins 1 and 2 (EN and GND) or move the jumper at J2 from pin 1 and pin 2 to pin 2 and pin3 to enable the output.
