Tool/software:

Hi ,

Need a solution for a book bust regulator , Vin is from 22-24V and Vout 28V

I see the LM5118-Q1 and the LM25118-Q1

Question is if there is any data on Space aplication tests for these devices? Or a suitable equivalent? ( I couldn't find anything on the EP series)

Hi Marcio,

sorry, we the LM25118-Q1 is not EP qualified.

Also the LM25118 is a Buck Boost but for your spec above you only need a Boost.

Best regards,

Stefan

My apologies, there was a typo on my specs….my input voltages are from 22 to 36 Volts and output voltage is 28v at 4 Amps … was trying for a non synchronous solution, but would you have any suggestions for a solution for space application? We really would like to use a TI part….
