by Graham Prophet @ edn-europe.com: LT8631 is a 1A, 100V-input-capable synchronous step-down switching regulator. Synchronous rectification delivers efficiency as high as 90% while Burst Mode operation keeps quiescent current under 7µA in no-load standby conditions. Its 3V to 100V input voltage range suits it for 48V automotive systems, dual battery transportation, industrial and 36V to 72V […]
