LTC3672BEDC-2#TRMPBF

Overview

The LTC3672BEDC-2#TRMPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It integrates three independent buck converters and one low-dropout linear regulator (LDO) within an 8-lead DFN package. The device operates with an input voltage range of 2.7V to 5.5V. Each buck converter provides a programmable output voltage, while the integrated LDO offers a fixed 1.8V output. The component supports a switching frequency up to 2.7MHz and includes features such as power good indicators and soft-start functionality for stable system startup.

Feature Summary

• Integrates three high-efficiency synchronous buck converters and one low-noise LDO in a compact footprint
• Provides independent output control with individual power good status signals for each regulator channel
• Supports wide input voltage ranges suitable for single-cell lithium-ion battery applications

Applications

• Portable consumer electronics requiring multiple regulated voltage rails
• Single-cell lithium-ion battery powered devices
• Embedded systems with space-constrained power management requirements

Procurement Notes

Verify the specific suffix designation carefully during procurement. The part number indicates a tape and reel packaging configuration. Confirm that the selected variant matches the required output specifications and thermal performance for your application environment before finalizing orders.

Selection Notes

Select this component when a multi-rail power solution is needed from a single input source. It is suitable for designs requiring both switched and linear regulation to minimize noise-sensitive analog sections. Ensure the total current demand across all channels remains within the device's thermal limits.

Part Context

This part belongs to the LTC3672 family of mixed-signal power management ICs. It combines switching regulators with a linear regulator to optimize efficiency and noise performance. The DFN package allows for small board area usage compared to discrete solutions.

Replacement Considerations

The LTC3672BEDC-1#TRPBF is a related variant within the same family. Verify if the specific output configurations or pin assignments differ between these suffixes before substitution.
