LT8580HMS8E#TRPBF

Overview

The LT8580HMS8E#TRPBF is a switching voltage regulator manufactured by Analog Devices Inc., housed in an MSOP-8 package. It supports Boost, SEPIC, and Inverting topologies with a 1 A output current capability. The device operates within an input voltage range of 2.9 V to 40 V and delivers adjustable output voltages from 1.204 V to 65 V. Key electrical parameters include a fixed 1.5 MHz switching frequency, a maximum static current of 1.2 mA, and an operating temperature range spanning -40°C to +150°C.

Feature Summary

• Supports multiple converter topologies including boost, SEPIC, and inverting configurations for flexible power design.
• Integrates a high-voltage switch rated at 65 V to accommodate wide input voltage ranges.
• Features soft-start functionality to manage inrush currents during startup sequences.

Applications

• Battery-powered systems requiring efficient voltage step-up or inversion
• Industrial control circuits utilizing SEPIC topology for variable input sources
• Automotive electronics needing robust operation across extended temperature ranges

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when placing orders. Confirm that the H-grade designation meets the required thermal performance specifications for your application environment. Ensure compatibility with the MSOP-8 footprint during PCB layout finalization. Cross-reference the datasheet for any recent product change notifications affecting pinout or electrical characteristics before procurement.

Selection Notes

Select this component when designing circuits that require a single IC to handle boost, SEPIC, or inverting functions without external topology changes. The 1.5 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1.2 mA quiescent current if battery life is a critical constraint. Verify that the 65 V switch rating exceeds the maximum expected peak voltage in your specific circuit configuration.

Part Context

This part belongs to the LT8580 family of DC/DC converters designed for versatile power management applications. It shares core architecture with other variants like the LT8580IDD#TRPBF but differs in package type and temperature grade. The MSOP-8 form factor provides a compact solution for space-constrained designs while maintaining thermal efficiency through integrated heat dissipation paths.
