I am trying to release a DW1000-based design to production.
In this design, the 1.8V TI LM3671MF-1.8 based switched-mode-power-supply (SMPS) includes the Taiyo Yuden CKP20162R2M-T 2.2uH inductor, which my client recalls was specified in the reference design from DecaWave. However, I cannot confirm that, because I cannot find a DW1000-based reference design schematic.
As it turns out, the Taiyo Yuden CKP20162R2M-T is going EOL. It has a very small footprint for 2.2uH, 1.2A and 140mOhm, and I cannot find another similarly-spec’ed inductor, with such a small footprint.
A) Is this part suggested by DecaWave for use in the 1.8V SMPS?
B) If so, can anyone suggest an alternate for this inductor?
