LT1374CR-5SYNC#TRPBF

Overview

The LT1374CR-5SYNC#TRPBF is a monolithic buck switching regulator from Analog Devices. It integrates a 4.5A switch and operates at a constant 500kHz frequency. The device accepts an input voltage range of 5V to 25V and provides a fixed 5V output. It features cycle-by-cycle current limiting and a shutdown mode with 20µA quiescent current. The component is housed in a surface-mount DDPAK-7 package.

Feature Summary

Integrates a high-current 4.5A power switch for efficient step-down conversion
Operates at a constant 500kHz switching frequency to minimize external component size
Includes built-in cycle-by-cycle current limiting for protection
Supports synchronization and low-power shutdown modes

Applications

Local on-board voltage regulation in personal computers
Power supply stages for disk drives
Voltage regulation for portable hand-held devices
Space-constrained systems requiring small inductor solutions

Procurement Notes

Verify the exact suffix against the manufacturer's official documentation, as variations may exist between tape-and-reel and tube packaging formats. Confirm that the specific part number corresponds to the synchronous version intended for your design requirements. Ensure compatibility with the required operating temperature range and package dimensions before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5V output is required from a 5V to 25V input rail. It is suitable for designs prioritizing high efficiency and compact footprint due to the 500kHz operation. Consider the thermal performance of the DDPAK-7 package relative to the expected load current and ambient conditions.

Part Context

This part belongs to the LT1374 family of high-efficiency, constant-frequency step-down regulators. The series is designed to replace linear regulators in applications requiring higher efficiency and lower heat dissipation. The synchronous variant offers improved performance over non-synchronous versions by reducing conduction losses.
