The LT8640EUDC-1#PBF is a high-efficiency synchronous step-down regulator utilizing Silent Switcher architecture to minimize EMI/EMC emissions. It supports a wide input voltage range from 3.4V to 42V and delivers up to 5A of continuous output current. The LT8640-1 variant specifically features forced continuous mode operation, distinguishing it from the standard LT8640. It includes an ultralow 2.5µA quiescent current in Burst Mode, spread spectrum frequency modulation, and a fast minimum on-time of 30ns which allows for high step-down ratios at high switching frequencies.
