LT1376HVIS8#TRPBF

Overview

The LT1376HVIS8#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5 V to 30 V and delivers a maximum output current of 1.5 A. The device features a fixed switching frequency of 500 kHz and supports adjustable output voltages. It incorporates a shutdown function and maintains a low quiescent current of 20 uA. The component is housed in an SOIC-8 surface-mount package and is rated for operation within a temperature range of -40 C to +125 C.

Feature Summary

• Integrated high-voltage buck converter topology supporting up to 30 V input
• Adjustable output voltage capability with fixed 500 kHz switching frequency
• Low power consumption featuring 20 uA quiescent current and shutdown mode

Applications

• Industrial control systems requiring isolated or non-isolated step-down regulation
• Battery-powered equipment utilizing high-input voltage sources
• Embedded systems needing efficient power management from 5 V to 30 V rails

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing this component. Confirm that the HV variant meets the required 30 V input limit for your application, as standard versions may differ. Ensure compatibility with the SOIC-8 footprint during PCB layout. Cross-reference the datasheet for thermal performance requirements under maximum load conditions.

Selection Notes

Select this part when an adjustable output is required from an input voltage up to 30 V. The 1.5 A current rating suits moderate power applications where efficiency is critical. Consider the 500 kHz frequency for balancing component size against switching losses. The wide operating temperature range makes it suitable for harsh environments compared to commercial-grade alternatives.

Part Context

This component belongs to the LT1376 series of high-voltage switching regulators. It shares architectural similarities with the LT1376IS#PBF but differs in input voltage tolerance and package configuration. The HV designation specifically denotes enhanced input capabilities up to 30 V, distinguishing it from lower-voltage variants within the same product family.

Replacement Considerations

LT1376HVCS8#PBF offers identical electrical specifications in a different SOIC-8 package format.
