Updated: 2026-07-15

Overview

The LT3580IMS8E#TRPBF is a step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices). This integrated circuit is designed to efficiently boost input voltages to higher output levels, making it suitable for a variety of power management applications. With its compact MSOP-8 package, the LT3580IMS8E#TRPBF offers space-saving solutions for modern electronic designs. It operates across a wide input voltage range and delivers stable output with high efficiency, making it popular in both industrial and consumer electronics.

Structure and Working Principle

The LT3580IMS8E#TRPBF integrates a switching regulator controller, power MOSFET, and necessary control circuitry into a single chip. It operates on the principle of pulse-width modulation (PWM) to achieve voltage conversion. When powered, the internal oscillator drives the power switch at a fixed frequency. The inductor stores energy during the switch-on period and releases it during the switch-off period, effectively stepping up the input voltage. Feedback circuitry maintains precise output voltage regulation.

Key Features

The LT3580IMS8E#TRPBF offers several notable features including a wide 2.5V to 16V input range and the ability to generate output voltages up to 34V. Its high switching frequency (up to 2.4MHz) allows for the use of small external components. Efficiency is a standout feature, reaching up to 90% in typical applications. The device also includes built-in protection features such as soft-start, current limiting, and thermal shutdown, enhancing system reliability.

Application Areas

This converter is commonly used in battery-powered systems where voltage boost is required, such as in portable medical devices, industrial sensors, and handheld instruments. Its compact size makes it ideal for space-constrained applications. In consumer electronics, the LT3580IMS8E#TRPBF finds use in LED drivers, USB power delivery systems, and various display power supplies. Automotive applications include infotainment systems and advanced driver assistance systems (ADAS) where stable power conversion is critical.

Maintenance and Precautions

Proper thermal management is essential for reliable operation. The MSOP-8 package has limited thermal dissipation capability, so adequate PCB copper area should be allocated for heat sinking. When designing with this IC, pay special attention to the layout of high-frequency switching paths. Keep input and output capacitors close to the device, and minimize loop areas in high-current paths to reduce EMI and ensure stable operation.

B2B Procurement Guide

When procuring the LT3580IMS8E#TRPBF in bulk, verify the manufacturer's part number carefully as similar parts may have different specifications. Consider purchasing from authorized distributors to ensure genuine components. Lead times may vary depending on market conditions, so plan your inventory accordingly. For prototyping or small quantities, sample kits from manufacturers or distributors can be cost-effective. Always check for the latest datasheet revisions before finalizing designs.
