2.1 Input/Output Connector Descriptions

Jx1, Pin 1 and 2 – VINPositive input connection from the input supply for the EVM
Jx1, Pin 3 and 4 – S+/S-Input voltage sense connections. Measure the input voltage at this point.
Jx1, Pin 5 and 6 – GNDInput return connection from the input supply for the EVM
Jx2, Pin 1 and 2 – VOUTOutput voltage connection
Jx2, Pin 3 and 4 – S+/S-Output voltage sense connections. Measure the output voltage at this point.
Jx2, Pin 5 and 6 – GNDOutput return connection
JPx1 – ENEN pin input jumper. Place the supplied jumper across ON and EN to turn on the IC. Place the jumper across OFF and EN to turn off the IC.
JPx2 – MODEMODE pin input jumper. Place the supplied jumper across PWM and MODE to operate in forced PWM mode. Place the jumper across PFM/PWM and MODE to operate in power save mode with an automatic transition to PWM mode at higher load currents.
