LT3992EFE#PBF

Overview

The LT3992EFE#PBF 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. The device supports switching frequencies from 110kHz to 2.5MHz and features a minimum output voltage of 0.8V. Designed for surface-mount installation in a 38-TFSOP package with an exposed pad, it functions within a junction temperature range of -40°C to 150°C.

Feature Summary

Dual independent output channels for simultaneous power delivery
Wide input voltage compatibility supporting high-voltage sources
Adjustable switching frequency for optimized efficiency and component size
Integrated synchronous rectification for improved thermal performance

Applications

Industrial equipment power distribution
Telecommunications infrastructure systems
Automotive electronics modules

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through manufacturer declarations. Ensure the ordering part number matches the required lead frame finish and moisture sensitivity level before finalizing procurement orders.

Selection Notes

Select this controller when dual isolated or non-isolated outputs are required from a single high-voltage rail. Evaluate the maximum load current requirements per channel to ensure the 3A limit is not exceeded. Consider the operating temperature range to verify suitability for harsh industrial environments exceeding standard commercial limits.

Part Context

This component belongs to the LT3992 family of dual synchronous buck controllers. It shares architectural similarities with other high-voltage regulators but is distinct in its dual-channel configuration. The device complements single-output variants by providing compact solutions for multi-rail power architectures without requiring multiple separate controllers.
