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-rigi
d 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.
