2.3 Jumper Information

JP1 – EN

EN pin input jumper. Place the supplied jumper across ON and EN to turn on the module. Place the jumper across OFF and EN to turn off the module.

With the jumper installed across ON and EN, users can create a precise turn-on voltage with R2 and R17. Keep the value of R2 above 15kΩ.

JP2 – PG PullupPG pin pullup voltage jumper. Place the supplied jumper on JP2 to connect the PG pin pullup resistor to VIN. Alternatively, the jumper can be removed and a different voltage can be supplied on pin 1 to pull up the PG pin to a different level. This externally applied voltage must remain below 6.5V.
JP3 and JP5 – VSET1VSET1 setting jumper. Place the supplied jumper on either JP3 and JP5 but not both.
JP4 and JP6 – VSET2VSET2 setting jumper. Place the supplied jumper on either JP4 and JP6 but not both.

To properly set the start-up voltage, the two jumpers for VSETx must be set before VIN is applied. Changing the jumpers after VIN is applied has no effect.

WARNING:
Before applying VIN, verify that both jumpers are installed: to JP3 or JP5 and to JP4 or JP6.
Do not leave the VSETx pins floating.
