LT8582EDKD#PBF

Overview

The LT8582EDKD#PBF is a dual DC/DC switching regulator manufactured by Analog Devices Inc., housed in a 24-WFDFN package with exposed pad. It supports Boost, Cuk, Flyback, and SEPIC topologies to provide positive or negative adjustable outputs ranging from 2.5V to 42V. The device features two independent channels, each capable of delivering up to 3.3A switch current. It operates within an input voltage range of 2.5V to 22V and includes a shutdown function. The integrated controller allows for programmable switching frequencies between 200kHz and 2.5MHz. It functions reliably across a junction temperature range of -40°C to +125°C.

Feature Summary

• Dual-channel architecture providing independent positive or negative output regulation
• Supports versatile topologies including Boost, Cuk, Flyback, and SEPIC configurations
• Integrated fault protection mechanisms for enhanced system reliability
• Programmable switching frequency range enabling optimization for size and efficiency

Applications

• Industrial control systems requiring isolated or non-isolated power rails
• Automotive electronics demanding wide input voltage tolerance
• Telecommunications infrastructure equipment
• Portable devices utilizing battery sources with varying charge levels

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration. The #PBF suffix indicates tube packaging, whereas #TRPBF denotes tape and reel. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when dual independent regulators are needed within a single footprint. Evaluate the maximum switch current requirement against the 3.3A limit per channel. Consider the 24-DFN package dimensions for PCB layout constraints. Verify that the input voltage range aligns with the source supply characteristics. Check thermal performance requirements given the operating temperature range limits.

Part Context

This part belongs to the LT8582 series of dual DC/DC converters designed for high-density power applications. It complements other Analog Devices PMIC solutions by offering flexible topology support. The series targets designs requiring multiple regulated voltages from a single input source. Development tools like the DC1734A demo board are available for evaluation.

Replacement Considerations

LT8582EDKD#TRPBF serves as the tape-and-reel equivalent of this tube-packaged component.
