LT80604AAFOA/VY+T

LT80604AAFOA/VY+T is the automotive-grade 4 A variant of the LT80604A Silent Switcher step-down regulator, converting 3 V to 65 V inputs in a 17-lead 3 mm by 4 mm QFN package. The A/VY code adds the features automotive production lines ask for: side-wettable flanks so solder joints can be verified by automatic optical inspection, and spread-spectrum frequency modulation that spreads switching energy to cut EMI peaks on top of the family's already quiet Silent Switcher architecture. Quiescent current of 8 microamp protects parked-vehicle and always-on budgets, and the -40 degrees C to +150 degrees C range covers engine-compartment and body-electronics placements. Wide-input coverage means the same regulator family can serve 12 V and 48 V vehicle rails and industrial 24 V buses. Selection advice: choose this code over the standard LT80604AAFO+T when your production process requires AOI-inspectable joints or your EMC plan benefits from spread spectrum; if the rail needs more than 4 A, the LT80605AAFOA/VY+T carries the same automotive package features at 5.5 A.
