QUICK START PROCEDURE

The development boards are easy to set up to evaluate the performance 
of the eGaN FET. Refer to figure 2 for proper connect and measurement 
setup and follow the procedure below: 
1.  With power off, connect the input power supply bus to +V

IN 

 

(J5, J6) and ground / return to –V

IN

 (J7, J8). 

2.  With power off, connect the switch node of the half-bridge OUT  

(J3, J4) to your circuit as required.

3.  With power off, connect the gate drive input to +V

DD

 (J1, Pin-1) 

and ground return to –V

DD

 (J1, Pin-2). 

4.  With power off, connect the input PWM control signal to PWM 

(J2, Pin-1) and ground return to any of the remaining J2 pins.

5.  Turn on the gate drive supply – make sure the supply is between 

7 V and 12 V range.

6.  Turn on the bus voltage to the required value (do not exceed the 

absolute maximum voltage on V

OUT

  as indicated in the table be-

low:

 

a.  EPC9060, 40 V

 

b.  EPC9061, 60 V

 

7.  Turn on the controller / PWM input source and probe switching 

node to see switching operation.

8.  Once operational, adjust the bus voltage and load PWM control 

within the operating range and observe the output switching  

behavior, efficiency and other parameters.

9.  For shutdown, please follow steps in reverse.

NOTE. When measuring the high frequency content switch node (OUT), care must be 

taken to avoid long ground leads. Measure the switch node (OUT) by placing the oscil-

loscope probe tip through the large via on the switch node (designed for this purpose) 

and grounding the probe directly across the GND terminals provided. See figure 3 for 

proper scope probe technique.
