Measuring 3 mm x 6 mm in a 28-lead QFN package, the LT8612 42V-input synchronous step-down switching regulator delivers a 6A output. Synchronous rectification delivers efficiency as high as 95% while Burst Mode operation keeps quiescent current under 3µA in no-load standby conditions. Price for the LT8612EUDE starts at $4.95 each/1,000. An industrial temperature version, the LT8612IUDE, with a -40°C to +125°C operating junction temperature costs $5.45 each/1,000.
