LT1374CR-5#PBF

Overview

The LT1374CR-5#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with a fixed 500kHz switching frequency and accepts an input voltage range of 5V to 25V. The device provides a fixed 5V output at up to 3.6A load current, utilizing a 4.5A internal switch. Key electrical parameters include a 2.5mA operating supply current and a 20µA shutdown current. It features cycle-by-cycle current limiting and is housed in a DDPAK-7 surface-mount package.

Feature Summary

Fixed 500kHz constant switching frequency for reduced external component size
Integrated 4.5A power switch with cycle-by-cycle current limiting
Low quiescent current operation with dedicated shutdown capability
Synchronous rectification compatible design for high efficiency

Applications

Point-of-load regulation for portable handheld devices
On-board voltage conversion for disk drives
Power management in personal computer systems
General DC-to-DC step-down conversion in space-constrained electronics

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the DDPAK-7 package dimensions match your PCB footprint requirements. Ensure the fixed 5V output aligns with system needs, as adjustable variants exist within the same series. Check manufacturer documentation for latest REACH SVHC status updates.

Selection Notes

Select this part when a fixed 5V output is required from a 5V to 25V input rail. The 500kHz frequency allows for smaller inductors compared to lower-frequency regulators. Consider thermal performance in the DDPAK-7 package if operating near maximum current limits. Verify that the 3.6A continuous output current meets the application's peak and steady-state demands.

Part Context

This component belongs to the LT1374 family of high-efficiency step-down switching regulators. The LT1374 series is designed for applications requiring high current density and compact solution sizes. Variants within the family offer different output voltages or adjustable settings, but the CR-5 variant specifically targets standard 5V distribution networks.
