Applications
LT3745EUJ-1 is used on board power rails, industrial 12 V/24 V supplies, and point-of-load converters. Confirm VIN/VOUT, current, and the QFN-40 thermal pad before layout. Nearby bucks/LDOs need compensation and footprint review.
Procurement notes
Confirm the full ordering code, package (QFN-40), and quantity on RFQ. SJ Chip replies with stock, condition, and lead time. Nearby MPNs are for evaluation only.
