LT3580IDD

Overview

The LT3580IDD is a DC-DC switching regulator IC manufactured by Analog Devices Inc. It integrates a 2A power switch and supports Boost, Cuk, SEPIC, and Inverting topologies. The device operates with an input voltage range of 2.5V to 32V and provides an adjustable output up to 42V. It features a programmable switching frequency from 200kHz to 2MHz and includes soft-start functionality. The component is housed in an 8-lead DFN package (3mm x 3mm) with an exposed pad for thermal management.

Feature Summary

Integrates a high-current 2A internal power switch for efficient power conversion.
Supports multiple converter topologies including boost, inverting, Cuk, and SEPIC configurations.
Features programmable switching frequency synchronization capability.

Applications

Industrial control systems requiring isolated or non-isolated negative rail generation
Battery-powered devices utilizing SEPIC topology for wide input voltage ranges
Embedded systems needing compact boost converters with soft-start capabilities

Procurement Notes

Verify the specific suffix 'IDD' confirms the 8-lead DFN (3x3mm) package variant when sourcing. Ensure compatibility with the required operating temperature range and confirm that the exposed pad connection meets your PCB thermal design specifications for proper heat dissipation during operation.

Selection Notes

Select this component when a single IC must support flexible topologies such as inverting or SEPIC rather than standard buck/boost only. The integrated 2A switch allows for higher current handling compared to lower-rated alternatives. Consider the DFN package size constraints and thermal requirements relative to the application's power density needs.

Part Context

The LT3580 series belongs to Analog Devices' portfolio of versatile DC-DC converters designed for space-constrained applications. It combines multiple converter functions into one chip, reducing component count. The IDD designation specifically identifies the DFN package version within the broader LT3580 family.
