概述

Description

The LT8620EMSE#TRPBF is a high-efficiency, monolithic step-down switching regulator from Analog Devices, previously Linear Technology. It is designed to deliver up to 2.5A of continuous output current from inputs ranging between 3.4V to 42V, making it suitable for a variety of applications including automotive, industrial, and distributed power systems.
The device uses synchronous rectification to achieve efficiency as high as 96%. It operates at a fixed frequency of 2MHz, but this can be adjusted to accommodate specific application needs. The LT8620EMSE#TRPBF features Burst Mode® operation, significantly reducing quiescent current to around 2.5µA, which is ideal for battery-powered devices.
Additional features include output soft-start, short-circuit protection, and a power-good flag. Its compact, thermally enhanced 12-lead MSOP package makes it suitable for applications where space is a constraint. The regulator also offers excellent line and load transient response, minimizing output voltage deviation during load changes.

Features

The LT8620EMSE#TRPBF is a high-efficiency, synchronous step-down regulator from Analog Devices. It features a wide input voltage range from 3.4V to 42V, making it versatile for various applications. The device can deliver up to 2.5A of continuous output current and operates with a minimum on-time of just 30ns, which allows for high switching frequencies and compact solution size.
Key features include a low quiescent current of 2.5µA during operation, which is ideal for battery-powered applications. It also offers fast transient response and excellent line and load regulation. The regulator supports adjustable output voltages as low as 0.97V. The LT8620EMSE#TRPBF integrates a high-efficiency power switch and catch diode, reducing component count and simplifying design.
The device employs a Burst Mode operation at light loads to maintain high efficiency and minimize power loss. Protection features include over-temperature and over-current protection. It is housed in a compact, thermally enhanced MSOP-16 package with an exposed pad for improved thermal performance. Overall, it is suitable for applications like automotive, industrial, and communications systems.
