LT1374HVIS8#PBF

Overview

The LT1374HVIS8#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with a fixed 500 kHz switching frequency and supports an input voltage range of 5 V to 32 V. The device provides an adjustable output voltage between 2.42 V and 27.52 V, delivering a switch current of 4.5 A. It features a low operating supply current of 2.5 mA and a shutdown current of 20 µA. The component is housed in an 8-SOIC package and functions within a junction temperature range of -40°C to +125°C.

Feature Summary

Integrates a high-current 4.5 A power switch for efficient step-down conversion
Maintains constant 500 kHz switching frequency to minimize external component size
Supports shutdown mode with ultra-low quiescent current consumption
Includes cycle-by-cycle current limiting for robust protection

Applications

Industrial point-of-load regulation
Battery-powered systems requiring high efficiency
Telecommunications power distribution
Embedded control board power supplies

Procurement Notes

Verify the specific suffix and tape/reel or tube packaging configuration against the official datasheet before ordering. Confirm that the 8-SOIC package dimensions match the target PCB footprint. Ensure the thermal management design accommodates the specified junction temperature limits under maximum load conditions.

Selection Notes

Select this regulator when a compact solution is required for high-current applications. The fixed 500 kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the input voltage does not exceed the 32 V maximum rating. Consider thermal performance if operating near the upper temperature limit.

Part Context

This component belongs to the LT1374 series of monolithic buck regulators. The series is characterized by high efficiency and the integration of power switches. The HVIS8 variant specifically denotes the high-voltage input capability and the SOIC-8 surface-mount package format suitable for space-constrained designs.
