LT8610ACHMSE-1#PBF

Overview

The LT8610ACHMSE-1#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 42 V and delivers up to 3.5 A of output current. The device features a fixed output voltage of 41.8 V and utilizes a switch frequency between 1.5 MHz and 2.2 MHz. Quiescent current is specified at 17 uA, and the component supports operation within a temperature range of -40°C to +150°C. It is housed in a 16-lead MSOP package.

Feature Summary

• Synchronous buck topology for high efficiency
• Wide 42V input voltage capability
• Integrated shutdown control

Applications

• Industrial power systems
• Telecommunications infrastructure
• Point-of-load regulation

Procurement Notes

Verify the complete part number including suffixes such as #PBF for lead-free status and specific thermal grades. Confirm package type matches design requirements. Check manufacturer documentation for latest revisions and compliance certifications before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 41.8V output is required from a wide input range. Ensure thermal management supports the 150°C junction limit. Compare quiescent current specifications against system standby requirements. Verify compatibility with external compensation networks if operating outside standard conditions.

Part Context

This part belongs to the LT8610AC series of micropower synchronous buck regulators. It shares architectural similarities with other LT8610 variants but differs in fixed output voltage and extended temperature rating. The AC grade indicates specific performance characteristics defined by Analog Devices for industrial applications.

Replacement Considerations

LT8610ACHMSE-1#TRPBF offers identical electrical specifications in tape-and-reel packaging instead of tube.
