The Enpirion product line has been the "go to" for our DC/DC converter needs for many years. It was first used in the RCE generation 3 development 10+ years ago because of its low PCB footprint area. After the RCE development, we have been using it for other TID-ID related designs (LCLS-II, LCLS DAQ, LDMX, LSST, etc).
Original Enpirion was originally owned by Altera. Later Altera was bought by Intel. In September 2021, Intel announced that it will
...
depreciate their entire "Enpirion" product line with no replacement OPN
...
. The last time to buy was March 18, 2022.
In September 2021, we did a survey of all TID-ID PCB BOMs to identify which ones were using Enpirion product line. After identifying the PCB designs using this DC/DC converter, we contacted all the PCB designers to inform them about the depreciation. We also asked the PCB designers the following questions:
From that questionnaire we have create tables for those 3 category types below.

If you do NOT see your PCB design listed in the tables below, then your PCB design does NOT use Enpirion product line and not affected by this depreciation |
