LT3580EMS8E#PBF

Overview

The LT3580EMS8E#PBF is a monolithic switching regulator IC manufactured by Analog Devices Inc., housed in an 8-lead MSOP package with an exposed thermal pad. It integrates a high-voltage power switch and supports Boost, Cuk, SEPIC, and Inverting topologies. The device operates with an input voltage range of 2.5V to 32V and delivers up to 2A of switch current. It features a programmable switching frequency from 200kHz to 2MHz, adjustable output voltage starting at 5V, and includes soft-start functionality. The component is rated for operation across a junction temperature range of -40°C to 125°C.

Feature Summary

Integrates a 2A power switch supporting multiple DC/DC converter topologies including boost, inverting, Cuk, and SEPIC configurations.
Features a wide input voltage operating range from 2.5V to 32V with a programmable switching frequency between 200kHz and 2MHz.
Includes integrated soft-start capability to limit inrush current during startup sequences.

Applications

Battery-powered systems requiring flexible step-up or inversion capabilities
Industrial control circuits utilizing SEPIC or Cuk topologies for variable input sources
Negative voltage generation for analog signal conditioning

Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm the exact packaging configuration and compliance status. Ensure that the procurement channel provides valid traceability records for the component lot. Cross-reference the ordering part number with the latest datasheet revisions to confirm pinout compatibility and electrical specifications match the design requirements before finalizing the purchase order.

Selection Notes

Select this component when a single IC solution is required for complex topologies such as SEPIC or Cuk converters. The choice is appropriate for designs needing a 2A switch current capacity within a compact 8-MSOP footprint. Consider the thermal performance of the exposed pad layout for heat dissipation. Verify that the required switching frequency falls within the 200kHz to 2MHz programmable range to meet EMI and efficiency targets.

Part Context

This part belongs to the LT3580 family of switching regulators designed for versatile power conversion applications. It shares architectural similarities with other Linear Technology derived parts but is distinct in its specific 2A switch rating and 32V input limit. The MSOP-EP package variant provides a balance between thermal management and small form factor suitable for dense PCB layouts.
