About PowerRef

Verified component reference for power electronics engineers

PowerRef exists because finding a trustworthy answer to "can this part do X in my circuit?" takes too long. Datasheets are buried in PDFs. Distributors show prices, not application guidance. Forums have opinions. Nothing aggregates verified, citable specs at part-number level.

Every spec on this site traces directly to a distributor API response or manufacturer datasheet — not a reseller's marketing copy, not a forum post. Source badges on each row show exactly where the value came from.

What's here

Datasheet quick-reference pages — spec tables with per-row source provenance, when-to-use and when-not-to-use guidance, minimum external components, and design equations
Component comparisons — side-by-side trade-offs at part-number level, with a direct recommendation on which to pick and why
Design guides — component sizing and selection walkthroughs with worked examples and real part numbers

Coverage

Current focus is general power electronics: buck converters, LDOs, gate drivers, power MOSFETs, current sense amplifiers, and protection components. SiC/GaN and isolated topologies are next.

How specs are sourced

Each component is ingested from the Digi-Key and Mouser APIs, then cross-referenced against the manufacturer datasheet. Specs are tagged with a provenance tier:

api — value from distributor API (Digi-Key / Mouser structured data)
table — extracted from a datasheet electrical characteristics table
llm — extracted from datasheet prose; lower confidence, verify before use

Pages with fewer than 8 verified specs are held for review and not published.
