LT1976HFE#TRPBF

Overview

The LT1976HFE#TRPBF is a high-voltage synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.3V to 60V and provides an adjustable output voltage from 1.25V to 55.2V. The device delivers up to 1.5A of continuous output current through its integrated synchronous N-channel MOSFETs. It utilizes a fixed 200kHz switching frequency and features a 16-lead TSSOP package with an exposed thermal pad for efficient heat dissipation. The component supports operation across a junction temperature range of -40°C to +125°C.

Feature Summary

Integrated synchronous rectification using internal N-channel MOSFETs to maximize efficiency without external Schottky diodes.
High input voltage capability allowing direct regulation from standard 48V bus architectures.
Fixed 200kHz switching frequency enables the use of small passive components.
Thermal performance optimized via exposed pad package design.

Applications

Industrial point-of-load regulation
Telecommunications power distribution
Automotive electronics systems

Procurement Notes

Verify the specific suffix 'HFE' against official documentation, as it may indicate extended temperature or reliability grades distinct from standard variants. Confirm that the '#TRPBF' designation aligns with required tape-and-reel packaging and lead-free compliance standards before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring high input voltages up to 60V with moderate current demands around 1.5A. The fixed 200kHz frequency is suitable for applications prioritizing component size over ultra-low noise. Ensure adequate thermal management is provided due to the power dissipation characteristics inherent in high-voltage buck topologies.

Part Context

This part belongs to the LT1976 family of high-voltage synchronous buck regulators. It shares core architectural similarities with other members like the LT1976IFE but differs in package configuration and potentially environmental ratings. The family is designed for robust performance in demanding industrial and automotive environments.
