LT3992IUH#PBF

Overview

The LT3992IUH#PBF is a dual-output synchronous step-down DC/DC converter 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 features a wide switching frequency range from 110kHz to 2.5MHz and supports a minimum output voltage of 0.8V. Packaged in a 32-WFQFN exposed pad, it functions as a positive regulator suitable for industrial applications within a junction temperature range of -40°C to 125°C.

Feature Summary

Dual independent output channels for simultaneous power rail generation
Wide input voltage capability supporting high-voltage distribution systems
Adjustable switching frequency allows optimization for efficiency or size
Integrated synchronous rectification for improved conversion efficiency

Applications

Industrial distributed power architectures
Point-of-load regulation for embedded processors
Telecommunications equipment power supplies
Automotive infotainment and control modules

Procurement Notes

Verify the specific suffix IUH against the official datasheet to confirm the temperature grade and package variant. Ensure compatibility with the required thermal management solution for the 32-WFQFN package. Cross-reference the manufacturer's latest revision history for any pinout or electrical specification updates before finalizing the bill of materials.

Selection Notes

Select this component when dual isolated or non-isolated rails are required from a single high-voltage source. Evaluate the thermal performance requirements given the 3A per channel capability in the QFN package. Confirm that the external inductor selection aligns with the desired switching frequency range to meet ripple and transient response specifications.

Part Context

This part belongs to the LT3992 family of dual synchronous buck converters designed for high-efficiency power conversion. It complements other Linear Technology regulators by offering dual-channel integration in a compact footprint. The series targets applications requiring multiple voltage levels from a common bus without separate controller complexity.
