Overview
The LT8610ACEMSE#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 adjustable output voltage starting from 3V minimum input, with a fixed reference of 0.8V. Switching frequency is programmable between 200kHz and 2.2MHz. It utilizes a 16-lead MSOP package with an exposed pad for thermal management. Quiescent current is specified at 17µA. The component supports shutdown functionality and operates 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 operation enhances battery life in standby modes
- Exposed pad package 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 TRPBF indicates tape and reel packaging configuration. Confirm the AC grade designation matches required electrical tolerances and temperature specifications. Ensure the 16-MSOP-EP footprint aligns with PCB layout guidelines. Cross-reference datasheet revision history for any material or marking changes documented in recent Product Change Notifications.
Selection Notes
Select this variant when input voltages exceed standard 36V limits but remain below 42V. The AC grade offers specific performance characteristics distinct from other LT8610 family members. Consider the 17µA quiescent current for applications prioritizing low standby consumption over ultra-low noise requirements. Evaluate thermal performance based on the exposed pad soldering requirements for optimal heat transfer.
Part Context
This component belongs to the LT8610A series of micropower synchronous buck regulators. It shares architectural similarities with the LT8610AB and LT8610IMSE variants but differs in specific electrical parameters such as quiescent current and output voltage references. The LT8610AC represents a specific grade within the broader LT8610 product line designed for robust industrial and automotive environments.
Replacement Considerations
LT8610ACIMSE#TRPBF serves as a direct pin-compatible alternative with identical electrical specifications but different packaging format. LT8610ACEMSE#PBF provides the same core functionality in tube packaging. Verify compatibility with evaluation boards such as DC2012A during transition.
