LTC3672BEDC-2

Overview

The LTC3672BEDC-2 is a power management IC featuring an integrated triple synchronous step-down DC/DC converter and three low-dropout linear regulators (LDOs). Designed for high-density applications, it operates from an input voltage range of 2.7V to 5.5V. The device integrates a 1MHz switching frequency for the buck converters, allowing for the use of small external inductors and capacitors. It provides independent output voltage adjustment for each regulator channel, supporting various logic levels and analog loads within a compact 8-lead WDFN package.

Feature Summary

• Integrates three synchronous buck converters and three LDOs in a single package
• Supports wide input voltage range suitable for single-cell lithium battery or 5V rail applications
• Features adjustable switching frequency and independent output regulation for each channel

Applications

• Portable electronic devices requiring multiple voltage rails
• Industrial control systems with mixed analog and digital loads
• Communication equipment needing compact power solutions

Procurement Notes

Verify the specific suffix BEDC-2 against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure compatibility with your PCB footprint and thermal requirements. Cross-reference the datasheet revision date to guarantee access to the latest reliability data and application notes before finalizing procurement.

Selection Notes

Select this component when space constraints require consolidating multiple discrete regulators into one solution. Evaluate the total current demand across all six channels to ensure the package can handle the thermal dissipation. Compare the quiescent current specifications against battery-operated system requirements to optimize efficiency during standby modes.

Part Context

This part belongs to the LTC3672 family of integrated power management solutions. It complements other multi-rail regulators by offering combined switching and linear regulation capabilities. The family targets applications where board area is limited but multiple distinct voltage outputs are necessary for complex system architectures.

Replacement Considerations

Check for direct substitutes such as the LTC3672BEDC-1#PBF or other variants within the same series. Verify that alternative packages maintain the same thermal performance and pin configuration to avoid redesigning the printed circuit board layout.
