LT8610ACHMSE#TRPBF

Overview

The LT8610ACHMSE#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. Switching frequency is programmable between 200kHz and 2.2MHz. Quiescent current is specified at 17µA. The component supports operation temperatures from -40°C to +150°C TJ. It is housed in a 16-lead MSOP package with an exposed pad for thermal management.

Feature Summary

• Integrated synchronous rectification for high efficiency across load ranges
• Programmable switching frequency allows optimization for size or performance
• Low quiescent current consumption enhances battery life in standby modes
• Extended temperature rating supports operation in harsh environments

Applications

• Industrial equipment power distribution
• Automotive electronics systems
• Point-of-load regulation modules
• Battery-powered portable devices

Procurement Notes

Verify the specific suffix 'CHMSE' against the manufacturer datasheet to confirm pinout compatibility and thermal characteristics. Ensure the ordering code matches the required tape and reel packaging format. Cross-reference the date code and lot number with recent production change notices to verify material consistency. Confirm that the exposed pad connection meets your PCB thermal design requirements.

Selection Notes

Select this part when input voltages exceed standard 36V limits but remain below 42V. The 3.5A current rating suits moderate power applications requiring compact solutions. Consider the wide operating temperature range if ambient conditions are extreme. Evaluate the trade-off between higher switching frequencies and electromagnetic interference levels during system design.

Part Context

This component belongs to the LT8610 family of micropower buck regulators. It shares architectural similarities with the LT8610AB and LT8610AC series but differs in specific thermal ratings and package variants. The 'C' designation typically indicates a specific temperature grade or feature set within the broader product line managed by Analog Devices.

Replacement Considerations

LT8610ACHMSE-1#PBF is a documented variant within the same family offering similar electrical specifications.
