2 Setup
This section describes how to properly use the TPS62806-7-8EVM083.
2.1 Input/Output Connector Descriptions
Jx1, Pin 1 and 2 – VIN Positive 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 – GND Input return connection from the input supply for the EVM.
Jx2, Pin 1 and 2 – VOUT Output 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 – GND Output return connection.
JPx1 – VSEL/MODE
VSEL/MODE pin input jumper. Before startup, leave the jumper floating to
select the output voltage corresponding to the installed Rx1 or Rx2 value.
Alternatively, connect the jumper between VSEL/MODE and PFM to select
the output voltage corresponding to that shown in
Table 1 . After startup,
connect this jumper between VSEL/MODE and PFM to operate with highest
efficiency or between VSEL/MODE and PWM to operate with lowest ripple.
JPx2 – EN
EN 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.
NOTE: Changes to JPx1 during operation only affect the operating mode (PFM or PWM) and have
no effect on the output voltage. To achieve a different output voltage, it is required to disable
and re-enable the device.
2.2 Setup
To operate the EVM, set jumpers JPx1 and JPx2 to the desired position per Section 2.1 . Connect the
input supply to Jx1 and connect the load to Jx2.
