The LT8640, from Analog Devices, is a compact, ultralow emission, high efficiency, and high speed synchronous monolithic step-down switching regulator. It is designed for use in sensitive applications such as automotive or industrial, where minimal EMI emissions are desirable.
This step-down regulator features Silent Switcher® architecture designed to minimize EMI emissions while delivering high efficiency at frequencies up to 3MHz. An ultra-low2.5µA 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 VIN to low VOUT 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).
