J1, Pin 1, 2 and 3 – VINPositive input connection from the input supply for the EVM
J1, Pin 4, 5 and 6 – GNDInput return connection from the input supply for the EVM
J2, Pin 1, 2 and 3 – VOUTOutput voltage connection
J2, Pin 4, 5 and 6 – GNDOutput return connection
J3, Pin 1 and 2 GNDGND pin headers to facilitate probing of signals
JP1 – ENEN pin input jumper. Place the jumper across ON and EN to turn on the IC.
Place the jumper across OFF and EN to turn off the IC.
JP2 – MODEMODE pin jumper. At startup, the jumper should not be used in order to enable a good readout of the voltage level at VSET/MODE pin. After startup, in normal operation, place the jumper across PFM and MODE to select the PFM operation. Place the jumper across FPWM and MODE to select the forced PWM mode.
JP3 - PGThe PG output appears on pin 2 of this header. Place a jumper across VOUT and PG to connect the PG pin to the output voltage through a 100kΩ resistor. Place a jumper across VIN and PG to connect the PG pin to the input voltage through a 100kΩ resistor.
