Description
The LT8612EUDE is a high-efficiency, monolithic step-down switching regulator designed by Analog Devices (formerly Linear Technology). It features an input voltage range of 3V to 42V, making it suitable for a wide variety of applications, including automotive and industrial systems. The device can deliver up to 5A of continuous output current with an adjustable output voltage range from 0.97V to 15V.
One of the standout features of the LT8612EUDE is its fast transient response, which is achieved through its high-frequency operation and short minimum on-time of just 30ns. This allows it to maintain a stable output voltage even with rapidly changing load conditions. It also has a low quiescent current of only 2.5µA, which helps extend battery life in portable applications.
The regulator incorporates internal compensation and a high-efficiency synchronous rectification, resulting in efficiencies as high as 96%. Additional features include soft-start, precise enable, power good flag, and thermal shutdown. The LT8612EUDE is available in a compact thermally enhanced 16-lead MSOP package.
