4.2 Start-Up Procedure

  1. Ensure that the jumper at JP1 (Enable control) pins 1 and 2 are covered to shunt EN to GND, disabling the output.
  2. Apply appropriate VIN voltage to VI (J1-2) and GND (J1-1).
  3. Move the jumper at JP1 (Enable control) pins 1 and 2 (EN and GND) to enable the output.
