Jumper NumberFunctionPlacementComment
JP1Buck1 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
JP2Buck2 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
JP7I2C addressI2C address configuration pin. Connect this pin to GND to set address 0x60H; connect it to Vcc to set address 0x61H; leave it open to set address 0x62HOn board Vcc is 6.25 V
JP8ModeOperation mode control pin. Connect this pin to GND to set forced PWM mode; leave the pin open to set auto PSM-PWM; connect this pin to Vcc set the IC to run in current share mode.
JP9I2C PowerPower connected to the I2C IO pull-up resistor; Leave the two pins un-connected set the power to be 3.3V from the I2C interface adaptor; short the two pins set the power to be Vcc.On board Vcc is 6.25 V
JP15I2C interface connectorPin 5 is 3.3 V from adaptor; pin 6 is Ground; pin 9 is SCL, pin 10 is SDA.
