Buyer and engineer answers
What must be established before ordering
Statements below are scoped to the named manufacturer source. Commercial availability is deliberately separate.
Package and ordering
XL4013 uses TO252-5L. XL4013E1 and a 2,500-per-reel packing statement belong to the exact ordering record, not the base model alone.
IC and application boundary
Choose against XL4015 using current, package and thermal requirements, not only the headline ampere number.
Publication safeguard
The claim boundary travels with the page.
Any efficiency number must include the input, output and load conditions from the manufacturer graph or table.
