LT1374HVCR#TRPBF

Overview

The LT1374HVCR#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with a constant 500kHz switching frequency and integrates a high-power switch capable of delivering up to 4.5A. The device accepts an input voltage range from 5V to 32V and provides an adjustable output voltage. Key electrical parameters include a maximum output current of 4.5A, a typical supply current of 2.5mA, and a shutdown current of 20µA. It utilizes current-mode control with pulse width modulation for stable regulation.

Feature Summary

Integrates a high-current 4.5A power switch within the monolithic die
Operates at a fixed 500kHz switching frequency to minimize external component size
Supports cycle-by-cycle current limiting for robust protection
Features low quiescent current and deep shutdown capability

Applications

Local on-board voltage regulation in personal computers
Power supplies for disk drives
Voltage regulation for portable hand-held devices
High-efficiency step-down conversion in space-constrained systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the operating temperature range aligns with system requirements, as industrial variants may differ from commercial grades. Cross-reference the manufacturer part number directly with Analog Devices to avoid counterfeit components.

Selection Notes

Select this component for applications requiring high output current and compact solution size due to the 500kHz frequency. It is suitable where input voltages reach up to 32V. Consider thermal management capabilities of the D2PAK package for high-load scenarios. Evaluate the need for synchronization features if multiple converters operate in proximity.

Part Context

This part belongs to the LT1374 family of step-down switching regulators. It shares architectural similarities with other members like the LT1374CR but differs in voltage ratings and packaging options. The HV designation typically indicates extended input voltage capabilities compared to standard variants. It serves as a core power management IC for DC-DC conversion tasks.
