LT8640/LT8640-1 Step-Down Regulators

Analog Devices Inc. LT8640/LT8640-1 Step-Down Regulators feature Silent Switcher architecture designed to minimize EMI/EMC emissions while delivering high efficiency at frequencies up to 3MHz. An ultralow 2.5µA quiescent current—with the output in full regulation—enables applications requiring the highest efficiency at very small load currents. The LT8640/LT8640-1 allows high V_IN to low V_OUT conversion at high frequency with a fast minimum top switch on-time of 30ns. The SYNC/MODE pin selects between Burst Mode operation, spread spectrum mode, synchronization to an external clock, and either pulse-skipping (LT8640) or forced continuous mode (LT8640-1).
