LT8580EDD#PBF

Overview

The LT8580EDD#PBF is a DC-DC switching regulator manufactured by Analog Devices Inc., housed in an 8-WFDFN package with exposed pad. It supports Boost, Cuk, and SEPIC topologies with adjustable output voltage ranging from 1.2V to 65V. The device features a switch current rating of 1.2A and operates within an input voltage range of 2.9V to 40V. Switching frequency is programmable between 200kHz and 1.5MHz. It provides positive or negative output configuration and functions across a junction temperature range of -40°C to 150°C.

Feature Summary

Supports multiple converter topologies including boost, inverting, and SEPIC configurations
Features integrated soft-start and synchronization capabilities for flexible system design
Provides adjustable output voltage control with high voltage switching capability

Applications

Industrial control systems requiring flexible power conversion
Battery-powered equipment utilizing SEPIC or boost architectures
Automotive electronics operating within wide input voltage ranges
Portable devices needing efficient step-up or inversion solutions

Procurement Notes

Verify the specific suffix #PBF indicates lead-free tape and reel packaging compliance with RoHS standards. Confirm the DFN-8 package variant matches your PCB footprint requirements. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Check datasheet revisions for any updates regarding thermal performance or electrical characteristics prior to final procurement.

Selection Notes

Select this component when application requires a single inductor solution for boost, SEPIC, or inverting topologies. Consider the 1.2A switch current limit against maximum load demands. Evaluate the 2.9V minimum input voltage against source availability. Verify that the 8-WFDFN package size fits within the available board area constraints while meeting thermal dissipation needs.

Part Context

This part belongs to the LT8580 family of synchronous switching regulators designed for versatile power management applications. It integrates a high-side N-channel switch and low-side N-channel switch for efficient operation. The family offers various package options including MSOP and DFN variants to suit different spatial and thermal requirements.
