Part Number: LM34936EVM

Hi,

I can not find D1 and D2 from BOM List.

Could you let me know these part numbers?

Hi Kuramochi,

Thanks for reaching out with your question.

I am checking with the engineer that designed the board and will get back to you shortly.

Hi Kuramochi-san,

My understanding is D1 and D2 are not used on the EVM. Do you see either one installed?

Please note that we will be able to offer follow-on support next week. Wish you a happy Thanksgiving!

Thanks,

Hi Kuramochi-san,

Sorry for the delay. I checked the actual BOM and D1 and D2 are installed.

D1: RSX501L-20TE25

D2: RB050L-60TE25

Both are by Rohm.

Actually these two diodes are not necessary on the EVM. Seemingly the design was coped over from any early design, and later we found not needed but somehow it was leftover in the final EVM. However, keeping them on does not cause the circuit to perform worse.

Thanks,

Youhao
