LM5045: Thermal dissipation per components

Hi Ella,

We didn't have related document which help analyze the thermal issue. I think customer need to use professional software to do thermal simulation such as ANSYS software.

Hi Jerry,

Is there a PSFB PWM controller device which is similar to LM5045 and provides Webench simulation?

As customer wants to take a reference for thermal calculation of full-bridge topology, I'm thinking to utilize Webench with other P/N. I found UCC28950 provided Webench simulation with the estimated thermal. But LM5045 is HSFB, the thermal estimation would be different to PSFB.

Hi, 

When can i expect to hear from you?

Hi

Except LM5045, the other device is designed for half bridge topology. If you want to look for PSFB controller, maybe you can try LM5046.
