Overview
The LT8610ABEMSE-5#PBF is a synchronous step-down switching regulator from the LT8610A series, manufactured by Analog Devices Inc. It operates with an input voltage range of 3.4 V to 42 V and delivers a fixed output voltage of 5 V at up to 3.5 A. The device features a low quiescent current of 2.5 uA and supports adjustable switching frequencies between 200 kHz and 2.2 MHz. It is housed in a 16-lead MSOP package with exposed pad and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Synchronous buck topology for high efficiency
- Low quiescent current operation
- Adjustable switching frequency capability
- Integrated shutdown control
Applications
- Industrial power systems
- Distributed power architectures
- Point-of-load regulation
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and tube packaging. Confirm the EMSE designation corresponds to the 16-lead MSOP package with exposed thermal pad. Ensure the AB grade matches required performance specifications. Cross-reference the manufacturer part number with official Analog Devices documentation to validate availability status and revision history before procurement.
Selection Notes
Select this component when a fixed 5 V output is required from a wide input voltage range up to 42 V. The 3.5 A continuous current rating suits moderate load applications. Consider the 16-MSOP package for space-constrained designs requiring thermal dissipation through an exposed pad. Verify that the internal switching frequency range aligns with external component selection constraints.
Part Context
This part belongs to the LT8610A family of micropower synchronous buck regulators. It shares architectural similarities with other members like the LT8610ABIMSE-5#PBF but differs in package type. The EMSE variant specifically utilizes the MSOP form factor, distinguishing it from TSSOP or QFN options within the same electrical specification group.
Replacement Considerations
LT8610ABIMSE-5#PBF offers identical electrical characteristics in a different package.
