This is the return connection for the output of converter 2.
This jumper enables or disables the converter. Connecting the shorting jumper between pins 1 and 2 (VIN
and EN) enables converter 2. Connecting the shorting jumper between pin 2 and 3 (EN and GND)
disables converter 2. Never leave this pin floating.

Connect the positive input power supply to J1 for converter number one or to J5 for converter number 2.
Connect the input power return (ground) to J2 for converter one or J6 for converter two. The
TPS622x0EVM-229 has an absolute maximum input voltage of 7 V. The recommended maximum
operating voltage is 6 V.
