TPS74401: WEBENCH simulation result error

Part Number: TPS74401

Hello expert,

Per checked with TPS74401 WEBENCH, the output voltage is not correct. After changed Cout, it is not fixed. The purpose is to simulate load transient based on customer's requirement. But it seems like WEBENCH has some error on it. please help on it and let me know if there is anything missing or need to add for your as reference. Thanks a lot!

Best regards,

Ann Lien

  • Hi Ann,

    Unfortunately WEBENCH is no longer supported for LDOs, so there is not a lot we can do to help here. Taking load transients with the EVM is the best way to get accurate data. Do they have the capability to do load transients with the EVM?
