LT1376HVCS8#TRPBF

Overview

The LT1376HVCS8#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc., housed in an 8-lead SOIC surface-mount package. It operates with an input voltage range from 5 V to 30 V and delivers a continuous output current of 1.5 A. The device features an adjustable output voltage, a fixed switching frequency of 500 kHz, and a shutdown function for power management. Quiescent supply current is 2.5 mA, while standby current drops to 20 uA. It supports operation across a temperature range of 0°C to +125°C.

Feature Summary

• Integrates a high-voltage buck converter topology capable of handling input voltages up to 30 V within a compact surface-mount package.
• Provides precise current regulation with a maximum output capability of 1.5 A for stable power delivery.
• Includes a dedicated shutdown pin to minimize quiescent current consumption during inactive periods.

Applications

• Industrial control systems requiring isolated or non-isolated DC-DC conversion
• Battery-powered equipment needing efficient step-down regulation
• Embedded systems utilizing microcontrollers with variable voltage requirements

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm tape-and-reel packaging configuration versus tube variants. Ensure the component matches the required thermal performance specifications for the intended operating environment. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require a wide input voltage range extending up to 30 V combined with moderate output current capabilities. Consider the 500 kHz switching frequency for balancing electromagnetic interference constraints against passive component size. Evaluate thermal dissipation requirements based on the SOIC-8 package limitations and the expected ambient temperature conditions of the final application.

Part Context

This part belongs to the LT1376 series of high-voltage switching regulators designed for robust performance in demanding environments. It serves as a solution for applications where standard low-voltage regulators are insufficient due to higher input line voltages. The series emphasizes efficiency and reliability in industrial and commercial power management designs.
