3.1 PD 3.0 Type-C tester
The PD3DB1548 PD 3.0 Type-C tester is shown in Fig 3.
Fig 3.
PD3DB1548 PD 3.0 Type-C tester
This board is used for PD 3.0 and 4.0(+) evaluation. A load and/or a voltage meter can
be connected to T2 and T3 to measure the output voltage and to draw current from the
USB-PD application with a resistive or electronic load.
The board is connected to the demo board via the Type-C port. The board can be
supplied by the Type-C application under test, but also via an ex5 V supply that is
connected to the micro USB port CN1.
The supply select switch needs to be set in the correct position. In the photograph the
switch is set for supply via the Type-C connection.
The board is connected to a charger application via the Type-C port.
For USB-PD 3.0 the board can be used to select the desired PDO by pressing the
corresponding switches. The on-board display shows the value of the output voltage
V(bus).
For USB-PD 4.0(+) this version of the Type-C tester will also work. Pressing V_Up or
V_down will increase or decrease the output voltage respectively with 20 mV steps.
Holding V_Up or V_Down pressed down will result in the maximum or minimum voltage
of the selected PDO respectively when PPS is enabled for that particular PDO.
