LT8610ABHMSE-5#TRPBF

Overview

The LT8610ABHMSE-5#TRPBF is a micropower synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range from 3.4 V to 42 V and delivers a fixed output of 5 V at up to 3.5 A. The device features a low quiescent current of 2.5 µA and supports adjustable switching frequencies between 200 kHz and 2.2 MHz. It is housed in a 16-lead MSOP package with an exposed pad, rated for junction temperatures up to +150°C.

Feature Summary

• Synchronous buck topology providing high efficiency across wide load ranges
• Micropower operation with ultra-low quiescent current for battery applications
• Integrated soft-start and shutdown control for system management
• Extended thermal performance suitable for high-temperature environments

Applications

• Industrial distributed power systems
• Battery-powered equipment requiring efficient step-down conversion
• Point-of-load regulation in compact form factors
• Automotive electronics operating within specified voltage limits

Procurement Notes

Verify the specific suffix #TRPBF confirms the reel packaging format required for automated assembly processes. Confirm that the AB grade meets the necessary temperature and electrical specifications for the target application environment. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure authenticity and correct revision level before finalizing procurement orders.

Selection Notes

Select this component when a fixed 5 V output is required from a high-voltage input source up to 42 V. The choice is driven by the need for high current capability combined with low standby power consumption. Consider the MSOP-16 package constraints regarding thermal dissipation and PCB layout requirements for the exposed pad to ensure reliable operation under maximum load conditions.

Part Context

This part belongs to the LT8610A family of micropower synchronous buck regulators. It shares core architectural features with other variants in the series, differing primarily in output voltage configuration and packaging style. The HMSE designation indicates a specific thermal-enhanced MSOP package variant designed for improved heat transfer compared to standard versions.

Replacement Considerations

LT8610ABHMSE-5#PBF offers identical electrical characteristics but utilizes tube packaging instead of tape and reel.
