LT1371CR#PBF

Overview

The LT1371CR#PBF is a high-efficiency switching voltage regulator manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 500 kHz and supports an input voltage range from 2.7 V to 30 V. The device delivers a maximum output current of 3 A through a single adjustable output channel. It features a low quiescent current of 4 mA and includes a shutdown function for power management. The component is housed in a DDPAK-7 surface-mount package and is rated for operation within a temperature range of 0°C to +125°C.

Feature Summary

Supports multiple converter topologies including boost, buck, Cuk, flyback, forward, and inverting configurations.
Provides high efficiency performance at a fixed 500 kHz switching frequency.
Integrates a shutdown pin for active power control.

Applications

Industrial power supply systems
Battery-powered equipment requiring efficient step-up or step-down conversion
Telecommunications infrastructure

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with thermal requirements for the DDPAK-7 housing. Confirm RoHS compliance status via the manufacturer's latest material declaration before integration into regulated assemblies.

Selection Notes

Select this component when a versatile single-output regulator capable of handling up to 3 A is required. It is suitable for designs needing support for various topologies such as SEPIC or inverting converters. Consider the 500 kHz frequency for balancing component size and efficiency needs.

Part Context

This part belongs to the LT1371 series of high-efficiency switching regulators. It shares architectural similarities with the LT1370 but offers a lower 3 A output current rating compared to the 6 A variant. Both devices utilize the same 500 kHz fixed frequency and similar topology flexibility.
