The JP2 jumper enables the device. By default, this jumper is set to the OFF position. If Vin>5.1V, put this jumper in the ON position to enable the output. Put this jumper in the OFF position to disable the output. If Vin<5.1V, connect EN to an external 3V power supply or adjust R3, R6 resistor values according to datasheet EV/UVLO function description, note that EN/UVLO pin max voltage is 6V.
