LT8610ACIMSE#PBF

Overview

The LT8610ACIMSE#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 3V to 42V and delivers up to 3.5A of output current. The device features adjustable output voltage starting at 0.8V, with a programmable switching frequency between 200kHz and 2.2MHz. It utilizes a 16-lead MSOP package with an exposed pad for thermal management. The component supports shutdown functionality and functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Integrated synchronous rectification for high efficiency across load ranges
• Programmable switching frequency allows optimization for size or performance
• Low quiescent current capability in shutdown mode
• Exposed pad design facilitates effective thermal dissipation

Applications

• Industrial control systems requiring isolated power rails
• Automotive electronics operating on 12V or 24V networks
• Point-of-load regulation for embedded processors
• Telecommunications infrastructure power distribution

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm the AC grade designation matches required thermal and electrical specifications. Check manufacturer documentation for recent package material changes or marking updates. Ensure compatibility with existing PCB footprint dimensions for the 16-MSOP-EP form factor before finalizing procurement.

Selection Notes

Select this component when input voltages exceed standard 36V limits but remain below 42V. The AC variant offers specific thermal characteristics suitable for dense layouts. Compare quiescent current requirements against system standby needs. Evaluate the maximum switching frequency options to balance electromagnetic interference constraints with external component sizing requirements.

Part Context

This part belongs to the LT8610 family of micropower synchronous buck regulators. The AC suffix typically denotes extended temperature or specific manufacturing lot variations compared to standard grades. It shares architectural similarities with other Silent Switcher devices but differs in input voltage tolerance and thermal performance metrics defined by the specific model code.

Replacement Considerations

LT8610ACIMSE-1#PBF serves as a fixed-output alternative within the same series. LT8610AIMSE#PBF represents a different thermal grade variant with similar pinout compatibility. Verify pin-to-pin equivalence and thermal resistance values before substituting.
