8.2.2.1 Slew Rate Selection

Adjust the turn-on slew rate of LMG367xR010 from approximately 10V/ns to 80V/ns, and adjust the maximum turn-off slew rate limit from 10V/ns to unlimited (controlled only by Ids). Refer to Section 7.3.1 for the details.

The slew rate affects GaN device performance in terms of:

  • Switching loss
  • Voltage overshoot
  • Noise coupling
  • EMI emission

Generally, high slew rates provide low switching loss, but high slew rates can also create higher voltage overshoot, noise coupling, and EMI emissions. Follow the design recommendations in this data sheet to mitigate the challenges caused by a high slew rate. The LMG367xR010 offers circuit designers the flexibility to select the proper slew rate for the best performance of applications.
