Vue d'ensemble

Description

The LTC3614IUDD is a high-efficiency monolithic synchronous step-down DC/DC converter designed by Analog Devices. It is capable of delivering up to 4A of continuous output current from a 2.25V to 5.5V input supply, making it suitable for applications requiring compact power solutions with high efficiency. The device operates with a fixed frequency and features peak current mode control for fast transient response and stability. It also includes a programmable output voltage, set via external resistors, and provides a power-good signal to indicate successful regulation.
Key features include low quiescent current in low-load conditions, burst mode operation to enhance efficiency at light loads, and thermal shutdown for protection. The LTC3614IUDD is housed in a compact 4mm x 4mm QFN package, making it suitable for space-constrained applications. It is commonly used in telecommunications, data communications, and general-purpose power supply designs.
