2.2 Start Up Procedure

  1. Make sure the EN jumper (J3) is open to connect the EN pin to the resistor divider from VIN.
  2. (Optional) Apply appropriate external bias voltage on VCC and PGND test points. If no external bias, please go directly to step 3. The external bias range is 3.1 V to 3.6 V.
  3. Apply appropriate VIN voltage to the VIN and PGND terminal J1.
