I
2
C Monitor Point and Alternate Connection
This header is provided to connect to or monitor the I
2
C signals on the TPS6236xEVM-655. If the I
2
C
signals are being sent via this header (and not via the USB-TO-GPIO adaptor), do not plug into the J8
header and provide a separate V
DD
supply on JP1 without any jumper installed.

Load Step Signal Input
This SMA connector accepts a signal input from a function generator that drives Q1 in order to evaluate
the TPS6236x's transient response.

V
DD
Control
This jumper is used to connect V
DD
to either a 3.3V rail provided by the USB-TO-GPIO adaptor (jumper
across pins 1 and 2) or to GND to reset the I
2
C registers (jumper across pins 2 and 3). Alternatively, the
user can provide their own V
DD
voltage (1.15 - 3.6V) between pins 2 and 3 of JP1. No jumper should be
installed in this case. For normal operation without an external supply voltage, the jumper should be
installed between pins 1 and 2.
2.1.12
JP2
–
VSEL0
This jumper sets the VSEL0 pin to either a logic high (jumper across pins 1 and 2) or a logic low (jumper
across pins 2 and 3).
2.1.13
JP3
–
VSEL1
This jumper sets the VSEL1 pin to either a logic high (jumper across pins 1 and 2) or a logic low (jumper
across pins 2 and 3).
2.1.14
JP4
–
EN
This jumper sets the EN pin to either a logic high (jumper across pins 1 and 2) or a logic low (jumper
across pins 2 and 3). When EN is low, the TPS6236x output will be off and not switching. Set EN to high
to turn on the output voltage.
