LT3580IDD#TRPBF

Overview

The LT3580IDD#TRPBF is a switching regulator IC from Analog Devices Inc., designed as a boost, inverting, or SEPIC DC/DC converter. It integrates a 2A power switch and supports adjustable output voltages ranging from 5V to 42V. The device operates with an input voltage range of 2.5V to 36V and features a programmable switching frequency between 200kHz and 2MHz. It includes soft-start functionality and is housed in an 8-DFN package with exposed pad for surface mount installation.

Feature Summary

Integrates a high-current 2A internal power switch for efficient energy transfer
Supports multiple topologies including boost, inverting, and SEPIC configurations
Features programmable switching frequency to optimize external component size
Includes integrated soft-start to limit inrush current during startup

Applications

Battery-powered systems requiring voltage step-up
Negative voltage generation from positive rails
Industrial control circuits with varying input sources
Portable equipment needing compact power solutions

Procurement Notes

Verify the specific suffix IDD against official Analog Devices documentation to confirm temperature grade and package variant. Ensure compatibility with required thermal dissipation standards for the DFN-8 footprint. Cross-reference the datasheet revision history for any recent parameter updates before finalizing procurement specifications.

Selection Notes

Select this component when a single-inductor solution is needed for boost, inverting, or SEPIC applications. The wide input voltage range suits diverse source conditions. Evaluate the 2A switch current limit against peak load requirements. Consider the 2MHz maximum frequency for minimizing passive component volume in space-constrained designs.

Part Context

This part belongs to the LT3580 family of monolithic switching regulators. The series is characterized by its versatility in handling various DC/DC conversion topologies within a small form factor. It targets applications demanding high efficiency and minimal external component count compared to discrete solutions.
