LT8610HMSE#TRPBF

Overview

The LT8610HMSE#TRPBF is a synchronous step-down DC/DC converter featuring an integrated 42V N-channel power switch. It supports input voltages from 3.8V to 42V and delivers output currents up to 5A with high efficiency across wide load ranges. The device operates at switching frequencies selectable between 100kHz and 750kHz, enabling the use of small external components. It includes programmable soft-start, current mode control, and comprehensive protection features such as overcurrent, thermal shutdown, and undervoltage lockout.

Feature Summary

• Integrated high-voltage N-channel power switch for simplified design
• Synchronous rectification for improved efficiency and reduced heat generation
• Flexible switching frequency selection to optimize component size and performance
• Built-in protection mechanisms including thermal shutdown and cycle-by-cycle current limiting

Applications

• Industrial automation systems requiring isolated or non-isolated power rails
• Telecommunications infrastructure equipment
• Point-of-load regulation in computing and networking hardware
• Battery-powered devices with wide input voltage ranges

Procurement Notes

Verify the exact part number suffix against manufacturer documentation to ensure correct tape-and-reel packaging and temperature grade. Confirm that the HMSE package variant matches your PCB footprint requirements. Cross-reference the datasheet revision date to ensure compatibility with latest electrical specifications and application notes provided by Analog Devices Inc.

Selection Notes

Select this component when designing high-efficiency buck converters requiring input voltages up to 42V. Ensure the chosen switching frequency aligns with inductor saturation current and output ripple voltage constraints. Verify that the thermal performance of the MSOP-10EP package suits the expected ambient temperature and load conditions without excessive heatsinking.

Part Context

This part belongs to the LT8610 family of synchronous step-down converters designed for industrial applications. It shares core architecture with other members but differs in package type and specific thermal characteristics. The family emphasizes robustness and ease of implementation for medium-power conversion tasks in demanding environments.

Replacement Considerations

Direct replacements include other LT8610 variants with different package options such as LT8610HMS#TRPBF if lead-free compliance or specific pin-out adjustments are required. Verify functional equivalence regarding switching frequency range and current limits before substitution.
