LT3992IFE#PBF

Overview

The LT3992IFE#PBF is a monolithic dual tracking synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 60V and provides two independent adjustable output voltages starting from 0.8V. The device delivers up to 3A per channel and supports switching frequencies between 110kHz and 2.5MHz. It features a 38-TSSOP-EP package with exposed pad for thermal management, ensuring reliable operation across temperatures from -40°C to +150°C junction temperature.

Feature Summary

Dual independent output channels with tracking capability
Synchronous rectification for high efficiency
Wide input voltage range supporting various bus standards
Integrated thermal protection and shutdown functionality

Applications

Industrial power distribution systems
Telecommunications equipment power supplies
Point-of-load regulation for digital signal processors
Automotive electronics power management

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure packaging integrity matches the tube specification indicated in official documentation. Cross-reference the full part number including suffixes to match exact electrical characteristics and package variant.

Selection Notes

Evaluate thermal performance based on PCB copper area and ambient conditions due to the 150°C junction limit. Select external components compatible with the 110kHz to 2.5MHz frequency range. Consider layout constraints for the 38-pin TSSOP-EP package to minimize parasitic inductance. Verify that the required output current does not exceed the 3A per channel rating under worst-case thermal scenarios.

Part Context

This component belongs to the LT3992 series of dual synchronous buck converters designed for high-current applications. It integrates control logic, drivers, and protection circuits into a single compact package. The series targets applications requiring isolated or non-isolated dual rails from a single input source, offering simplified design compared to discrete solutions.
