JP1BUCK3 enable (EN3)Connect EN3 to GND to disable VOUT3, connect EN3 to VIN through a 100-kΩ resistor to enable VOUT3; Leave open to enable VOUT3.
JP2PGOOD pull-upPGOOD pull-up resistor connected to the V7V; Leave the two pins un-connected set the pull-up voltage open; short the two pins set the pull-up voltage to be V7V.On board V7V is 6.3 V when VIN is 12 V
JP3RESET pull-upRESET pull-up resistor connected to the V7V; Leave the two pins un-connected set the pull-up voltage open; short the two pins set the pull-up voltage to be V7V.On board V7V is 6.3 V when VIN is 12 V
JP4ModePower sequencing mode control pin. Connect this pin to GND to set power sequence with dedicated enable pin; Connect this pin to V7V set the power sequence with the pre-defined power up and power down sequence.
JP31BUCK1 enable (EN1)Connect EN1 to GND to disable VOUT1, connect EN1 to VIN through a 100-kΩ resistor to enable VOUT1; Leave open to enable VOUT1.
JP32BUCK2 enable (EN2)Connect EN2 to GND to disable VOUT2, connect EN2 to VIN through a 100-kΩ resistor to enable VOUT2; Leave open to enable VOUT2.
