LT3471EDD#PBF

Overview

The LT3471EDD#PBF is a dual switching regulator from Analog Devices, housed in a 10-lead DFN package. It integrates two independent regulators capable of boost and inverting topologies within a single chip. The device operates with an input voltage range of 2.4V to 16V and delivers up to 1.3A output current per channel. It features a fixed 1.2MHz switching frequency and supports adjustable output voltages ranging from ±1V to 40V. The component includes shutdown functionality and operates across a temperature range of -40°C to +85°C.

Feature Summary

Integrates two independent switching regulators for simultaneous positive and negative rail generation
Supports multiple circuit configurations including boost, inverting, Cuk, and SEPIC topologies
Features a compact 3mm x 3mm DFN package designed for space-constrained applications

Applications

Dual-rail power supply generation for portable electronic devices
Powering operational amplifiers requiring split supply rails
Battery-powered systems needing both positive and negative voltage outputs

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm packaging type and environmental compliance. Ensure the ordering part number matches the required tape-and-reel or tube configuration. Confirm that the requested variant aligns with the intended thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when a design requires two isolated DC-DC converters in a minimal footprint. It is suitable for applications demanding high efficiency at moderate currents. Consider the 1.2MHz frequency for balancing component size and electromagnetic interference. Verify that the input voltage range covers the system's battery or supply profile.

Part Context

This part belongs to the LT3471 family of dual switching regulators. It is distinct from single-channel regulators like the LT3474 and other buck-only controllers. The device is categorized under PMIC switching regulators and is designed to simplify power architecture by combining two converters into one integrated circuit.
