Description of the Evaluation Board
The PGA26E07BA-SWEVB006 is a chopper evaluation board using a dedicated X-GaN driver
(AN34092B) for measuring the high speed switching characteristics of turn-on and turn-off of the X-
GaN power transistor. The dv/dt and di/dt using an inductive load can be measured by controlling
the X-GaN power transistor with an external signal. There are test terminals prepared for easy
monitoring of Vgs and Vds waveforms. To improve the accuracy of the current measurement, use
the mounted semi-rigid connector and connect to a 50Ω terminated oscilloscope input. The
evaluation board together with the user’s guide also serves as a reference design for the X-GaN
gate driver circuit and PCB layout.
Recommended Operating Conditions
Table 1 shows the operating conditions used to achieve the switching performance reported in the
Measurement Result. All the components used in the evaluation board are rated for the
recommended operating conditions only.
Please read the measurement procedure before starting the evaluation. It is necessary to refer to
the X-GaN transistor and driver datasheet when using this user’s guide. The detail operation of the
gate driver IC and the design of its peripheral components are described in the OPERATION
section of the datasheet.

*Use only burst mode function from the pulse generator. Do not use continuous pulse mode as
this will cause damage to the components and evaluation board.
**For VGS and VDS monitoring, use the coil wire mounted on the evaluation board to minimize
any ringing in the waveform.

Measurement Procedures
Initial steps:
Do all the necessary connection between the
evaluation board, components and equipment.
Connect DC power ①to P/N of the board
with the terminal block.
Connect pulse generator to the IN+/GND
terminal of the board.
The IN- terminal must be shorted to GND
and not possible to input any signal.
Connect DC power ②to VCC/GND terminal
of the board.
Probe the point where you want to monitor
and observe the waveform using oscilloscope.
Be careful not to short with other parts. Use the coil wire fixture mounted on the evaluation
board for VGS, VDS1 & VDS2 monitoring.
Start-up:
Set up the pulse generator with the amplitude 0-5V and having the double pulse profile as
shown below:
Table 4: Double Pulse Setting with L=95uH
Figure 9: Double Pulse Profile
Again, ensure that the pulse generated occurs only in the burst mode. If the pulse is generated
continuously, the transistor will be damaged by high current flows.
Set the DC power ②to 12V gradually.
Check VGS waveform when a double pulse is inputted from pulse generator. Please carry out
this step with DC power ①is set to 0V.
Then, the voltage of DC power ①is gradually increased from 0V to predetermined voltage
(400V). Monitor the VDS1 voltage with oscilloscope and confirm that the VDS1 voltage rises to
the set value.
Input a double pulse with the pulse generator again and check the VGS, VDS1 and IL
waveform.
Observation of waveform will be easier if the trigger is applied at the rising / falling edge of
VGS or VDS1 as shown on Figure 9 above.
If different inductor value is used other than the one provided, please set the pulse width until
the desired IL value is achieved.

Shutdown:
Set the DC power ①slowly to 0V and then follow by the DC power ②to 0V.
Turn off the power. Check the VDS waveform and ensure that the capacitor between P/N
terminals has fully discharged. There is risk of electric shock due to the residual charge.
Measurement of dV/dt for Turn On/Off Switching Characteristics:
The range used is 10%~90%
IL condition is set at 2.5A / 5A / 10A / 15A with 16 times averaging
Therefore, the dv/dt at turn on: 320V / T-on and
the dv/dt at turn off: 320V / Toff
