LT8610ACIMSE-1#TRPBF

Overview

The LT8610ACIMSE-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 an adjustable output voltage starting from 0.8V, with a maximum output capability of 41.8V. It supports a programmable switching frequency between 1.5MHz and 2.2MHz. The IC includes a low quiescent current mode drawing 17µA and offers thermal shutdown protection. It is housed in a 16-lead MSOP package with an exposed pad for enhanced thermal performance.

Feature Summary

• Integrated synchronous rectification for high efficiency across load ranges
• Programmable switching frequency allows optimization for size or efficiency
• Low quiescent current operation extends battery life in standby modes
• Thermal regulation protects the device during overload conditions

Applications

• Industrial equipment power distribution
• Telecommunications infrastructure systems
• Portable instrumentation power supplies
• Automotive electronics subsystems

Procurement Notes

Verify the specific suffix -1#TRPBF against official Analog Devices documentation to confirm the fixed frequency setting. Ensure the ordering part number matches the required package variant and tape-and-reel quantity 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 wide input voltage range up to 42V is required alongside high output current capabilities. The fixed frequency option simplifies electromagnetic interference filtering design compared to variable frequency models. Consider the thermal characteristics of the MSOP package and ensure adequate printed circuit board copper area is allocated for heat dissipation during continuous operation.

Part Context

This part belongs to the LT8610A family of micropower buck regulators designed for space-constrained applications. The AC grade indicates specific electrical parameter tolerances defined by the manufacturer. The IMSE designation specifies the 16-lead MSOP package configuration with an exposed thermal pad, distinguishing it from other package options within the same product line.

Replacement Considerations

LT8610ACIMSE#TRPBF serves as a functional equivalent within the same series but may differ in switching frequency characteristics. Verify pin compatibility and thermal resistance values before substitution. Consult official datasheets to ensure all electrical parameters meet the original design requirements.
