概述
Description
The LT8608EMSE#PBF is a high-efficiency, high-speed synchronous monolithic step-down regulator from Analog Devices, part of the Power by Linear™ series. It is designed to deliver up to 1.5A of continuous output current from input voltages ranging from 2.6V to 42V, making it suitable for automotive, industrial, and telecom applications. The LT8608 features a 2MHz switching frequency, allowing the use of small external components while maintaining high efficiency, with low ripple Burst Mode® operation reducing quiescent current to just 2.5µA. Its internal synchronous rectification aids in achieving efficiencies as high as 93%, while the fast minimum on-time of 45ns enables high step-down ratios even at high frequencies. The regulator also includes features such as internal compensation, a soft-start to limit inrush current, and overcurrent and thermal protection. Packaged in a thermally enhanced 10-lead MSOP, the LT8608EMSE#PBF is ideal for compact designs where space is a premium.
