LT8471EUFD#PBF

Overview

The LT8471EUFD#PBF is a dual-output DC/DC converter manufactured by Analog Devices Inc. It integrates two independent switching regulators, each capable of delivering up to 2A of output current. The device supports multiple topologies including buck, boost, and inverting configurations, allowing for flexible power rail generation from a single input source. Operating with an adjustable switching frequency up to 2MHz, it enables the use of compact external components. The IC features internal synchronization capability to reduce electromagnetic interference and improve system efficiency. Packaged in a thermally enhanced QFN-28 footprint, it is designed for applications requiring efficient multi-rail power management in space-constrained environments.

Feature Summary

• Dual independent 2A synchronous switching regulators
• Supports buck, boost, and inverting topologies
• Internal synchronization reduces EMI
• Adjustable switching frequency up to 2MHz

Applications

• Portable electronics requiring multiple voltage rails

Procurement Notes

Verify the exact suffix (EUFD#PBF) against the manufacturer's official datasheet to confirm package type and lead-free compliance. Ensure the ordering part number matches the specific temperature grade and packaging format required for your production line. Cross-reference with Analog Devices' official distribution channels to confirm current availability and authenticity before placing orders.

Selection Notes

Select this component when designing circuits that require two isolated or non-isolated power outputs from a single input source. Consider its dual 2A capability and multi-topology flexibility if your design involves generating both positive and negative voltages or stepping voltage up and down simultaneously. Evaluate thermal performance requirements given the QFN-28 package and ensure adequate PCB copper area for heat dissipation during high-load operations.

Part Context

The LT8471 belongs to Analog Devices' family of multitopology DC/DC converters, designed to simplify power supply designs by combining multiple converter functions into a single IC. This series targets applications where board space is limited and efficiency is critical. The EUFD variant specifically denotes the QFN-28 package configuration, distinguishing it from other pinout options within the same functional family.
