CSD19532Q5B: Recommendation for FETs

Part Number: CSD19532Q5B
Other Parts Discussed in Thread: LM5145, , CSD19534Q5A, CSD19533Q5A

We are using LM5145 this part with the low side FET (NTMFS015N10MCL) and the high side FET (FDMS86102LZ). However, the output voltage was abnormal. so we would like to know if there is any recommendation on the FETs to replace NTMFS015N10MCL and FDMS86102LZ. I found CSD19532Q5B is pretty much equivalent to NTMFS015N10MCL, but still would like get the recommendation.  

Here is the application: 

Input voltage range: 24~ 60 V

Output voltage:   12 V

Output current:  4~5 A max

Target topology: buck

Thanks. 

  • Hi Jack,

    Thanks for the inquiry. I would recommend the CSD19533Q5A (lower on resistance & higher gate charge) as a replacement for the NTMFS015N10MCL and the CSD19534Q5A (lower on resistance & similar charge) for the FDMS86102LZ. Please contact me via regular TI email to discuss this opportunity further.

    Best Regards,
