Description

The LT8608EMSE is a high-efficiency, monolithic step-down switching regulator designed by Analog Devices, part of their Power by Linear™ line. It is designed to convert a higher input voltage to a lower output voltage with high efficiency. The device operates over an input voltage range of 3V to 42V and can deliver up to 1.5A of continuous output current. The LT8608EMSE features a 200mV low dropout voltage, which allows the regulator to maintain output regulation with minimal input-output differential.
Key features include its Burst Mode® operation, which offers high efficiency at light loads, and a quiescent current of only 2.5µA, making it ideal for battery-powered applications. The switching frequency is programmable and can be set from 200kHz to 2.2MHz, which allows for optimization between efficiency and component size. The regulator is in a thermally enhanced MSOP package, which helps in handling thermal dissipation.
This device is suitable for applications in automotive, industrial, and distributed power systems where high efficiency, small solution size, and high reliability are critical.
