LT8610ACEMSE-1#PBF

Overview

The LT8610ACEMSE-1#PBF 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 a maximum output current of 3.5A. The device features a fixed output voltage of 41.8V and supports switching frequencies between 1.5MHz and 2.2MHz. It incorporates a shutdown function and maintains a quiescent current of 17µA. The component is housed in a 16-MSOP package with an exposed pad, suitable for surface mount installation across temperatures from -40°C to +125°C.

Feature Summary

• Synchronous buck topology providing high efficiency at 3.5A output
• Fixed 41.8V output configuration for specific rail requirements
• Integrated shutdown control for power management
• Wide operating junction temperature range

Applications

• Industrial equipment power distribution
• Telecommunications infrastructure supplies
• Automotive subsystem regulation

Procurement Notes

Verify the suffix #PBF indicates lead-free tape-and-reel packaging compliance. Confirm the EMSE designation matches the required 16-MSOP exposed pad footprint. Ensure the AC grade meets the specified thermal and electrical performance criteria for the target environment. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this variant when a fixed 41.8V output is required rather than adjustable regulation. The AC grade defines the specific electrical characteristics and temperature range. Consider the 16-MSOP package constraints for PCB layout. Evaluate the 1.5MHz to 2.2MHz frequency range against EMI requirements and external component sizing needs for the specific application design.

Part Context
