LT8610ACHMSE-1#TRPBF

Overview

The LT8610ACHMSE-1#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 42V and delivers up to 3.5A of output current. The device features a fixed internal feedback reference of 0.8V and supports adjustable output voltages. It utilizes a high-frequency switching architecture with a frequency range of 1.5MHz to 2.2MHz, enabling the use of small external components. The IC is housed in a 16-lead MSOP package with an exposed thermal pad for efficient heat dissipation.

Feature Summary

• Integrated synchronous rectification for high efficiency across load ranges
• Fixed high switching frequency reduces passive component size
• Wide input voltage capability supports various power sources
• Thermal performance optimized via exposed pad package design

Applications

• Industrial control systems requiring isolated or non-isolated DC-DC conversion
• Point-of-load regulation for microprocessors and FPGAs
• Battery-powered equipment with wide input voltage variations
• Communication infrastructure power distribution networks

Procurement Notes

Verify the specific suffix -1#TRPBF against the official Analog Devices datasheet to confirm the fixed switching frequency variant. Ensure the ordering part number matches the required tape and reel packaging specifications. Cross-reference the manufacturer date code and lot traceability requirements with your supply chain standards before finalizing procurement orders.

Selection Notes

Select this component when a fixed high-frequency operation between 1.5MHz and 2.2MHz is required to minimize inductor size. Compare the 3.5A continuous current rating against peak load demands. Evaluate the thermal resistance of the 16-MSOP package against your PCB copper area constraints. Confirm that the 3V minimum input voltage aligns with your lowest expected supply rail conditions.

Part Context

This part belongs to the LT8610 family of micropower buck regulators designed for space-constrained applications. The AC grade indicates specific electrical performance characteristics defined by Analog Devices. The IMSE designation refers to the 16-lead MSOP package with an exposed pad, facilitating surface-mount assembly and thermal management on standard PCB layouts.

Replacement Considerations

LT8610ACIMSE-1#TRPBF shares identical electrical specifications and pinout compatibility. Verify package tolerance and marking differences if substituting. Other LT8610 variants may differ in switching frequency or current ratings; consult the datasheet for detailed parameter comparisons before implementation.
