TPSF12C3-Q1: Working with avionics line frequencies

Lorenzo Lutti

Part Number: TPSF12C3-Q1

Tool/software:

Hello, regarding this original thread (I hope there's a link somewhere) that took place a year ago and was closed "hanging", I'm also interested in this topic. I would like to use these devices in a 400 Hz three phase system instead of 50/60 Hz system. The device has an internal filter to reject 50/60 Hz to "maximize the useful voltage range of the low-voltage output at INJ", to quote the DS. Which would be the impact on performance by using it with line frequencies of 400 Hz?

Thank you!

Hi Lorenzo,

I had a look at your question. The TPSF12C3-Q1 IC should be able to reject line frequencies of 400Hz as well. you should be able to use it in your system. y

Here is a good resource for more questions on the implementation: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1257197/faq-tpsf12c1-and-tpsf12c3-power-supply-filter-ic-faqs.

Thanks and Regards,
