概述

Description

The LT8614EUDC#TRPBF is a high-efficiency, step-down voltage regulator designed by Analog Devices, formerly Linear Technology. It features a compact, 3mm x 3mm QFN package and operates with a wide input voltage range from 3V to 42V, making it suitable for automotive and industrial applications. The device can deliver up to 4A of continuous output current and achieves efficiencies up to 96%, thanks to its synchronous rectification design.
Key features include a fast minimum on-time of 30ns, allowing high step-down ratios at high switching frequencies. The LT8614 supports Burst Mode operation, which significantly improves efficiency at light loads by reducing quiescent current to as low as 2.5µA. Additional functionalities include a precise enable pin, power good flag, and internal compensation to simplify the design process.
Its operating frequency can be adjusted from 200kHz to 3MHz, enabling optimization for efficiency or solution size. The device also integrates robust protection features like thermal shutdown, current limit, and short-circuit protection. The LT8614EUDC#TRPBF is ideal for applications needing reliable performance in a space-constrained environment.
