LT1976EFE#TRPBF

Overview

The LT1976EFE#TRPBF is a high-voltage synchronous buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 3.3V to 60V and provides a single adjustable output ranging from 1.25V to 55.2V. The device delivers a continuous switch current of 1.5A and supports a fixed switching frequency of 200kHz. It utilizes a 16-TSSOP package with an exposed pad for thermal management and functions within a junction temperature range of -40°C to 125°C.

Feature Summary

Integrates a high-voltage N-channel power switch capable of handling up to 60V input
Features internal slope compensation to ensure stable operation across all duty cycles
Includes programmable soft-start to limit inrush current during startup
Provides cycle-by-cycle current limiting and thermal shutdown protection

Applications

Industrial point-of-load regulation
Automotive electronics systems
Distributed power architectures
Battery-powered equipment requiring high input voltage tolerance

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging with lead-free composition. Confirm the base part number LT1976EFE matches the required TSSOP-16 package variant. Ensure compatibility with the intended switching frequency and output voltage configuration before finalizing procurement orders.

Selection Notes

Select this component when a wide input voltage range up to 60V is required alongside moderate output current capabilities. The synchronous design improves efficiency compared to non-synchronous alternatives. Consider the 16-TSSOP package constraints for thermal dissipation requirements in the target application environment.

Part Context

This part belongs to the LT1976 family of high-voltage synchronous buck regulators. It shares core architectural features with other variants in the series, differing primarily in package type and shipping configuration. The family is designed for applications demanding robust performance under varying input conditions.
