LT8610AHMSE-5#TRPBF

Overview

The LT8610AHMSE-5#TRPBF is a micropower synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It features a fixed 5 V output and supports up to 3.5 A of continuous output current. The device accepts an input voltage range from 3.4 V to 42 V. It operates with a quiescent current of 2.5 uA and offers a programmable switching frequency between 200 kHz and 2.2 MHz. The component is housed in a 16-pin MSOP package with an exposed pad and functions within a temperature range of -40°C to +150°C.

Feature Summary

• Integrated high-efficiency synchronous rectification for optimized power conversion
• Ultra-low quiescent current capability for extended battery life in standby modes
• Flexible switching frequency adjustment to balance efficiency and component size
• Robust thermal performance supporting operation in high ambient temperatures

Applications

• Battery-powered portable electronic devices requiring efficient power management
• Industrial control systems and distributed power architectures
• Automotive electronics operating under wide voltage and temperature conditions
• Communication infrastructure equipment needing reliable DC-DC regulation

Procurement Notes

Verify the specific suffix and tape-and-reel packaging configuration against official Analog Devices documentation before procurement. Confirm that the fixed 5 V output variant matches the system requirements, as other adjustable or different voltage options exist within the LT8610A family. Ensure compatibility with the required MSOP-16 footprint and thermal pad soldering specifications during assembly planning.

Selection Notes

Select this part when a fixed 5 V rail is required alongside high input voltage tolerance up to 42 V. Consider the 3.5 A current limit for loads demanding significant power in a compact form factor. Evaluate the 2.5 uA quiescent current against system sleep mode requirements. Compare the MSOP-16 package constraints with available PCB area and thermal dissipation capabilities relative to other PMIC solutions.

Part Context

This component belongs to the LT8610A series of micropower buck regulators designed for applications where space and efficiency are critical. It integrates the controller, drivers, and synchronous switches into a single compact package. The series is engineered to provide stable regulation across wide input ranges while maintaining low noise and high efficiency typical of modern analog power management integrated circuits.
