Présentation

Description

The LT8614EUDC#TRPBF is a high-efficiency, high-speed synchronous monolithic step-down switching regulator produced by Analog Devices. It is designed to deliver up to 4A of continuous output current from a wide input voltage range of 3.4V to 42V, making it suitable for a variety of applications including automotive systems, industrial supplies, and distributed power systems.
Key features include a low quiescent current of 2.5µA in Burst Mode operation, which enhances efficiency at light loads, and a fast minimum on-time of 30ns, enabling high-frequency operation with small external components. The device includes internal compensation, soft-start, and a power-good flag to ensure robust performance. It also supports operation down to 100% duty cycle for low dropout conditions.
Packaged in a compact, thermally enhanced 3mm x 3mm DFN, the LT8614EUDC#TRPBF provides a high-performance power solution with minimal footprint, making it an excellent choice for space-constrained applications.

Features

The LT8614EUDC#TRPBF is a high-efficiency, synchronous step-down regulator designed by Analog Devices. It features a wide input voltage range from 3V to 42V, making it suitable for various applications, including automotive and industrial systems. The regulator can deliver up to 4A of continuous output current while maintaining high efficiency, thanks to its synchronous rectification.
Key features include its fast minimum on-time of only 30ns, which allows for high step-down ratios even at high switching frequencies. This enables the use of smaller inductors and capacitors, reducing overall solution size. The LT8614 also offers Burst Mode operation for increased efficiency at light loads, a low dropout performance, and a low quiescent current of only 2.5µA, which is beneficial for battery-operated devices.
Additional highlights include an adjustable switching frequency (200kHz to 2.2MHz), internal compensation, soft-start capability, and robust protection features such as thermal shutdown, short-circuit protection, and overvoltage lockout. The compact 3mm x 4mm DFN package supports efficient thermal management and easy PCB layout.
