LT8610ACHMSE#PBF

Overview

The LT8610ACHMSE#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 up to 3.5A of output current. The device features a fixed output voltage of 41.8V and supports switching frequencies from 1.5MHz to 2.2MHz. It utilizes a 16-lead MSOP package with an exposed thermal pad for efficient heat dissipation. The component functions within a junction temperature range of -40°C to +150°C and includes shutdown functionality.

Feature Summary

• Integrated synchronous rectification for high efficiency
• Wide input voltage capability supporting industrial standards
• High operating junction temperature rating for harsh environments
• Fixed output voltage configuration simplifies design

Applications

• Industrial power supplies
• Point-of-load regulation
• Automotive electronics
• Telecommunications equipment

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm the fixed 41.8V output requirement matches the application, as this variant lacks adjustability. Check for restricted supply status on distributor platforms before finalizing procurement plans.

Selection Notes

Select this part when a fixed 41.8V output is required rather than an adjustable version. The wide temperature range and high input voltage make it suitable for demanding industrial or automotive applications where standard components may fail.

Part Context

This component belongs to the LT8610 family of micropower synchronous buck regulators. It shares core topology with adjustable variants like the LT8610ACIMSE but differs in output configuration. The series is designed for high-efficiency DC/DC conversion in compact form factors.

Replacement Considerations

LT8610ACEMSE#PBF offers similar specifications but may differ in quiescent current characteristics.
