Buying FAQ — TPS5430DDAR

Answer-first notes for stock, authenticity, lead time and quoting. Marked up as FAQPage.

What does the DDAR suffix mean on TPS5430?

Package / reel ordering code for the PowerPAD SOIC. Always order by full MPN; DDA vs DDAR can affect packaging qty.

TPS5430 vs LM2596 — which is better for new designs?

TPS5430 is higher frequency, smaller magnetics and better efficiency in many mid-current rails. LM2596 is older / larger. We map both if you need second-source options.

Can you source TPS5430DDAR during allocation?

Yes — franchise leftover, authorized and vetted open market. Share approved alternates (e.g. other SWIFT bucks) to shorten ETA.

Do you provide reel vs cut-tape?

Both when stock allows. State SMT line needs (full reel / partial) in the RFQ so warehouse picks correctly.
