Jumper when installed can be used to enable the fast reverse recovery diode.



JP4

Jumper when installed can be used to add additional load to output.



JP5

Jumper when installed can be used to bypass the output gate resistor.



JP6

Jumper when installed used to accommodate common-cathode drive.

4.1. Voltage and Current Sense Test Points

The Si826x evaluation board has several test points. These test points correspond to the respective pins on the

Si826x integrated circuits as well as other useful inspection points. See Figures 7 through 10 for a silkscreen

overview. See schematics in Figures 11 through 14 for more details as well.
