USER GUIDE
UG530: Si82Ax-Cx Isolated Gate Driver EVB User Guide
This user guide covers a range of evaluation boards
(EVBs) for Skyworks' Si82Ax, Si82Bx, and Si82Cx
isolated gate drivers. These EVBs are designed to
evaluate and test the functionality and performance of
these gate drivers. They can be used in standalone
mode with an oscilloscope and the onboard dummy
capacitive load or connected to a switched mode
power supply (SMPS) controller and an external power
MOSFET for system-level evaluation.
These single-channel isolated gate drivers are available
in SSO-8 (6 kV isolation) and NB SOIC-8
RMS
(3.75 kV isolation) packages. The EVBs cover a wide
RMS
variety of Si82Ax-Cx series devices. However, some
features are only available on certain EVBs, depending
on the driver IC on the board. EVBs with Si82Ax and
Si82Bx devices allow for independent control of output
rise and fall times. Another EVB version with the
Si82Bx features a separate Miller clamp pin.

The Si82Cx EVB option includes Selectable Variable
Current Drive (SelVCD™), which allows for dynamic
adjustment of the rising/falling edge driving strength,
eliminating the need for external gate resistors. 
