LT3580HMS8E#PBF

Overview

The LT3580HMS8E#PBF is a monolithic switching regulator manufactured by Analog Devices Inc., housed in an 8-lead MSOP package with an exposed pad. It integrates a high-voltage power switch capable of delivering up to 2A of output current. The device supports multiple topologies including boost, inverting, and SEPIC configurations. It operates with an input voltage range from 2.5V to 32V and can generate adjustable output voltages up to 42V. The internal oscillator allows for switching frequencies between 200kHz and 2MHz. It features a low quiescent current of 1mA and includes soft-start functionality to limit inrush current during startup.

Feature Summary

Integrates a high-voltage power switch supporting boost, inverting, and SEPIC converter topologies
Provides adjustable output voltage capability with a maximum rating of 42V
Includes integrated soft-start mechanism to control startup slew rate and limit inrush current
Features programmable switching frequency ranging from 200kHz to 2MHz for optimization

Applications

Battery-powered systems requiring step-up or inverted voltage rails
Industrial control applications utilizing wide input voltage ranges
Portable equipment needing efficient DC-to-DC conversion
Automotive electronics operating within specified temperature extremes

Procurement Notes

Verify the specific suffix 'H' indicates military-grade temperature qualification (-55°C to +125°C) compared to standard industrial variants. Confirm the 'MS8E' package designation matches the required 8-lead MSOP footprint with exposed thermal pad. Ensure the '#PBF' suffix confirms lead-free and RoHS compliance status as per manufacturer specifications before finalizing procurement orders.

Selection Notes

Select this component when application requirements demand a single-chip solution for non-isolated DC-DC conversion with high voltage tolerance. The choice is appropriate for designs needing flexible topology options such as inverting or SEPIC converters alongside standard boost operation. Consider the thermal performance of the MSOP package with exposed pad for heat dissipation needs under full load conditions.

Part Context

This part belongs to the LT3580 family of switching regulators designed for versatile power management tasks. The series offers integrated switches to minimize external component count and board space. Variants within the family differ primarily by temperature grade and packaging options, providing flexibility for various commercial, industrial, and military applications requiring reliable power regulation.
