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 R18. Keep the value of R2 above 15kΩ.
JP2 – MODE/SYNC MODE/SYNC pin input jumper. Place the supplied jumper across PWM and MODE/SYNC to operate the IC in Forced PWM mode. Place the jumper across PFM/PWM and MODE/SYNC to operate the IC in PFM/PWM mode. Remove the jumper to apply a synchronization signal on the MODE/SYNC pin.
JP3 – PG Pull-up PG pin pull-up voltage jumper. Place the supplied jumper on JP3 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.
JP4 and JP7 – VSET1 VSET1 setting jumper. Place the supplied jumper on either JP4 and JP7 but not both.
JP5 and JP8 – VSET2 VSET2 setting jumper. Place the supplied jumper on either JP5 and JP8 but not both.
JP6 and JP9 – VSET3 VSET3 setting jumper. Place the supplied jumper on either JP6 and JP9 but not both.

To properly set the start-up voltage, the 3 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 all 3 jumpers are installed: to JP4 or JP7, JP5 or JP8, and JP6 or JP9.
Do not leave the VSETx pins floating.
