Overview
The LT8610ABEMSE#TRPBF is a synchronous step-down switching regulator from the Analog Devices LT8610A series, housed in a 16-lead MSOP package with an exposed pad. It accepts input voltages between 3.4V and 42V to provide adjustable output voltages starting from 0.97V. The device delivers up to 3.5A of continuous output current while maintaining a low quiescent current of 2.5µA. It supports programmable switching frequencies ranging from 200kHz to 2.2MHz and operates within a junction temperature range of -40°C to +125°C.
Feature Summary
- Integrated synchronous rectification for high efficiency across load ranges
- Ultra-low quiescent current consumption for extended battery life
- Programmable switching frequency allows optimization for size or performance
- BurstMode operation minimizes no-load power loss
Applications
- Industrial point-of-load regulation
- Automotive electronics systems
- Portable instrumentation power supplies
- Telecommunications infrastructure equipment
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the AB grade meets required automotive qualification standards if applicable. Ensure compatibility with LTpowerCAD design tools for accurate thermal and electrical simulation before finalizing procurement orders.
Selection Notes
Select this component when a wide input voltage range up to 42V is required alongside high current capability. The adjustable output feature provides flexibility for various rail requirements. Consider the MSOP-EP package for its balance of thermal performance and compact footprint in space-constrained designs.
Part Context
This part belongs to the LT8610A family of micropower buck regulators designed for demanding applications. It shares core architecture with variants like LT8610ABIMSE#TRPBF but differs in package type. The series is characterized by its ability to operate efficiently in both continuous and discontinuous conduction modes.
Replacement Considerations
Direct substitutes include LT8610AIMSE#TRPBF and LT8610ABIMSE#TRPBF. Verify pinout compatibility and thermal dissipation characteristics when swapping packages. Ensure output voltage adjustment ranges match the original circuit requirements.
