LT8471IUFD#PBF

Overview

The LT8471IUFD#PBF is a dual multitopology DC/DC converter manufactured by Analog Devices Inc. It integrates two independent switching regulators, each featuring a 2A switch, within a compact QFN-28 package. The device supports multiple configurations including buck, boost, inverting, and SEPIC topologies for both channels. Key electrical parameters include an input voltage range of 2.7V to 36V, adjustable output voltages, and a programmable switching frequency up to 2MHz. It offers high efficiency and low noise operation suitable for space-constrained designs.

Feature Summary

• Dual independent channels supporting flexible multitopology configurations such as buck, boost, inverting, and SEPIC.
• Integrated 2A power switches per channel enable high current density in a small footprint.
• Programmable switching frequency allows optimization for size and performance requirements.
• Synchronization capability permits linking multiple units or aligning with external clocks.

Applications

• Portable battery-powered equipment requiring multiple voltage rails
• Industrial control systems with mixed positive and negative supply needs
• Automotive electronics operating on wide input voltage ranges
• Telecommunications infrastructure boards

Procurement Notes

Verify the specific suffix IUFD indicates the industrial temperature grade and QFN-28 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ordering part numbers match exact thermal and pinout requirements for your PCB layout.

Selection Notes

Select this component when dual isolated or coupled supplies are needed from a single wide-range input. Evaluate thermal dissipation capabilities given the 2A switch rating and QFN-28 package constraints. Compare against single-channel solutions if only one rail is strictly necessary to optimize board space.

Part Context

This part belongs to the LT8471 family of dual multitopology converters. It shares functional similarities with other Linear Technology (now Analog Devices) dual converter series but distinguishes itself through its specific combination of 2A switches and wide input voltage tolerance. It serves as a versatile power solution for complex multi-rail architectures.

Replacement Considerations

LT8471EFE#PBF is a verified equivalent offering identical functionality and specifications. Verify that any alternative components maintain compatibility with the required input voltage range and thermal management strategies.
