Select devices for 48 V to 12 V / 6 V conversion in AI and general servers.
48 V remains the workhorse rack bus.
About 48 V Power Conversion
48 V remains the workhorse rack bus. Designers often choose 80 V or 100 V MOSFETs to keep avalanche and transient margin while chasing low RDS(on).
Use this page to connect 48 V conversion to IBC, MOSFET selection, and rack-level protection.

Supply Chain Considerations
Lifecycle and allocation
Long-life designs need current lifecycle status, last-time-buy windows, and a documented second source before a line goes NRND.
Lead time and date code
We check stock, factory lead time, date code, and packaging so buyers can accept or reject lots before they move.
Traceability
COC, photos, and manufacturer traceability are available on request for qualified and high-reliability programs.
Engineer and Procurement Paths
Use the same application page to select parts or to source a BOM.
Architecture to datasheet

Stock and lead-time check
Submit an MPN or BOM for availability, factory lead time, and alternate-channel options.
Date-code verification
Confirm date code, packaging, and lot identity before shipment.
Obsolete and hard-to-find parts
Source NRND, EOL, and allocation-risk devices with documented alternatives.
BOM-level sourcing
Cross-reference, lifecycle screening, and multi-line quotes from one application context.
