LT8582IDKD#PBF

Overview

The LT8582IDKD#PBF is a dual DC-DC switching regulator IC manufactured by Analog Devices Inc. It supports Boost, Cuk, Inverting (Buck-Boost), and SEPIC topologies with adjustable output voltages ranging from 2.5V to 42V. The device features two independent channels, each delivering up to 3.3A of switch current. It operates within an input voltage range of 2.5V to 22V and supports a switching frequency between 200kHz and 2.5MHz. Packaged in a 24-WFDFN (7x4mm) exposed pad surface-mount package, it functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

Supports multiple converter topologies including boost, Cuk, inverting, and SEPIC configurations for flexible power design.
Provides dual independent output channels capable of positive or negative voltage regulation.
Integrates high-current switching capability to support demanding load requirements.

Applications

Industrial control systems requiring isolated or non-isolated multi-rail power supplies
Automotive electronics needing robust voltage conversion under varying input conditions
Portable equipment utilizing battery sources with diverse voltage step-up or inversion needs

Procurement Notes

Verify the specific suffix IDKD against official Analog Devices documentation to confirm pinout and thermal pad configuration. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the 24-WFDFN package matches the target PCB footprint dimensions and soldering profile requirements before finalizing orders.

Selection Notes

Select this component when designing circuits requiring simultaneous positive and negative rails or complex topologies like Cuk or SEPIC. Evaluate the 3.3A switch current limit against peak load demands. Consider the 2.5MHz maximum switching frequency for minimizing passive component size while managing thermal dissipation in the DFN package.

Part Context

This part belongs to the LT8582 family of dual synchronous rectifier controllers designed for versatile power management applications. Unlike standard buck-boost regulators, it offers extended topology support. The IDKD variant specifies industrial temperature grading and a specific DFN package form factor suitable for compact, high-density electronic assemblies.
