2.1 Input/Output Connector and Header Descriptions

    J1, Pin 1 and 2 – VIN Positive input connection from the input supply for the EVM
    J1, Pin 3 and 4 – S+/S– Input Voltage sense connections. Measure the input voltage at this point.
    J1, Pin 5 and 6 – GND VIN GND return connection from the input supply for the EVM, common with J2, pin 5 and 6
    J2, Pin 1 and 2 – VOUT Output voltage connection
    J2, Pin 3 and 4 – S+/S– VOUT Output voltage connection
    J2, Pin 5 and 6 – GND VOUT GND return connection for the output voltage, common with J1 pin 5 and 6
    J3 – Enable Shorting the jumper between the center pin EN and HIGH turns on the unit. Shorting the jumper between the center EN and LOW turns the unit off.
    J4 – MODE Shorting the jumper between the center pin MODE and LOW enables automatic transition to power-saving mode at light-load currents as described in the data sheet. Shorting the jumper between the center pin MODE and HIGH enables forced PWM mode.
