2.1 Start-Up Procedure

  1. Verify that the jumper at J3 (Enable control) pins 1 and 2 are covered to shunt EN to GND, disabling the output.
  2. Make sure that the jumper at J4 (frequency control) pin-3 and 4 are covered to select 800kHz.
  3. Apply appropriate VIN voltage to VIN (J1-1) and GND (J1-2).
  4. Move the jumper at J3 (Enable control) away from pins 2 and 1 (EN and GND) to enable the output.
