Hi
Please tell me about the case where you want to install a snubber circuit on the MPM3515.
Customers want to install a snubber circuit on the MPM3515 as a noise countermeasure.
The MPM3515 has a SW terminal. Is it effective to provide a snubber circuit here? Is it okay to use it in that way?
Hi tatsuro_kishimoto,
Welcome to the MPS Technical Forum! A snubber circuit is a good solution for when the customer is seeing problematic ringing at the switch node. There should be no issue with connecting a snubber circuit to the MPM3515’s switch node. If the ringing is not an issue, the customer may still consider leaving unstuffed pads on their board for future testing.
