LT8610ABEMSE-5#TRPBF

Overview

The LT8610ABEMSE-5#TRPBF is a synchronous step-down switching regulator from the Analog Devices LT8610A series. It delivers a fixed 5 V output at up to 3.5 A with an input voltage range of 3.4 V to 42 V. The device features a low quiescent current of 2.5 uA and supports programmable switching frequencies between 200 kHz and 2.2 MHz. Packaged in a 16-lead MSOP with exposed pad, it operates reliably across temperatures from -40°C to +125°C.

Feature Summary

• Integrated synchronous buck topology for high efficiency
• Ultra-low quiescent current for extended battery life
• Programmable switching frequency for optimization
• Improved BurstMode operation for reduced ripple

Applications

• Industrial control systems
• Telecommunications infrastructure
• Portable instrumentation
• Embedded computing platforms

Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging distinct from tube variants like #PBF. Confirm the AB grade meets required thermal and electrical specifications. Validate RoHS compliance status through official documentation before finalizing procurement orders.

Selection Notes

Select this part when a fixed 5 V rail is required within a wide 42 V input window. The 3.5 A capability suits moderate load applications. Ensure the MSOP-16 package fits the board layout constraints. Consider the 2.5 uA standby current for power-sensitive designs requiring efficient shutdown modes.

Part Context

This component belongs to the LT8610A family of micropower synchronous buck regulators. It shares core architecture with variants such as LT8610ABIMSE-5#PBF but differs in package type and manufacturing lot handling. The AB designation indicates specific performance grading within the broader LT8610 product line.

Replacement Considerations

LT8610ABEMSE-5#PBF offers identical electrical characteristics in tube packaging.
