LT8610AIMSE-3.3#PBF

Overview

The LT8610AIMSE-3.3#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc., housed in a 16-lead MSOP package with an exposed thermal pad. It operates from an input voltage range of 3.4 V to 42 V and delivers a fixed output voltage of 3.3 V at up to 3.5 A. The device features a programmable switching frequency between 200 kHz and 2.2 MHz, ensuring low quiescent current of 2.5 µA during shutdown. It supports operation across an extended temperature range from -40°C to +125°C.

Feature Summary

Integrated synchronous rectification for high efficiency
Programmable switching frequency for optimized design flexibility
Low quiescent current consumption in shutdown mode
Exposed thermal pad for enhanced heat dissipation

Applications

Industrial control systems
Telecommunications infrastructure
Point-of-load (POL) regulation
Automotive electronics

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging. Confirm the IMSE designation corresponds to the industrial temperature grade (-40°C to +125°C). Ensure the -3.3 suffix matches the required fixed output voltage. Cross-reference the manufacturer's latest datasheet for any pinout or electrical specification updates prior to finalizing procurement orders.

Selection Notes

Select this component when a fixed 3.3 V output is required within a 42 V input system. The 3.5 A continuous current capability suits moderate power applications. Consider the MSOP-16 package constraints for PCB layout and thermal management. Evaluate the need for external frequency programming against noise sensitivity requirements in the target application environment.

Part Context

This part belongs to the LT8610A family of micropower buck regulators designed for space-constrained applications. The series offers high efficiency and low standby current, making it suitable for battery-powered and always-on systems. The LT8610AIMSE-3.3#PBF specifically provides a fixed 3.3 V output, distinguishing it from adjustable variants within the same product line.
