LT3992IUH#TRPBF

Overview

The LT3992IUH#TRPBF is a dual-output synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 60V and provides two adjustable output channels, each capable of delivering up to 3A of current. The device supports switching frequencies between 110kHz and 2.5MHz and features a minimum output voltage of 0.8V. Designed for high efficiency, it utilizes a 38-lead TSSOP package with an exposed pad for thermal management and functions within a junction temperature range of -40°C to 150°C.

Feature Summary

Dual independent output channels for simultaneous power rail generation
Wide input voltage compatibility supporting 3V to 60V sources
High-frequency operation capability up to 2.5MHz for compact designs
Integrated synchronous rectification for improved efficiency

Applications

Industrial equipment requiring multiple regulated voltage rails
Automotive electronics systems operating under wide voltage conditions
Telecommunications infrastructure power distribution units
Portable battery-powered devices needing efficient step-down conversion

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct packaging and temperature grade. Confirm that the 38-TSSOP footprint matches your PCB layout requirements. Check for any recent product change notifications regarding material or manufacturing site updates before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring two isolated or non-isolated low-voltage outputs from a higher voltage bus. Ensure the external inductor selection supports the desired switching frequency and load current without saturation. Verify that the thermal performance of the 38-lead package meets the application's heat dissipation needs under maximum load conditions.

Part Context

This part belongs to the LT3992 family of dual-channel synchronous buck controllers designed for versatile power management applications. It shares core architecture with other members of the series but differs in package type and specific electrical characteristics tailored for surface-mount assembly. The family emphasizes high efficiency and wide input voltage ranges suitable for demanding industrial and automotive environments.
