Overview
The LT8610AEMSE-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 provides 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 an 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
- Automotive electronics
- Telecommunications infrastructure
- Portable equipment power supplies
Procurement Notes
Verify part authenticity through authorized Analog Devices distributors or direct channels. Confirm RoHS compliance status via official documentation. Check for specific manufacturing lot codes if required for traceability. Ensure the ordering suffix matches the exact fixed output voltage requirement. Validate package type against design specifications 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 current rating suits moderate load applications. Consider the MSOP-16 package constraints for thermal management. Verify that the fixed output meets system requirements without needing external feedback resistors.
Part Context
This part belongs to the LT8610A family of micropower synchronous buck regulators. It shares core architecture with variants like LT8610ABEMSE-5#PBF but differs in specific performance optimizations. The EMSE suffix indicates the MSOP-16 package variant. It is designed for applications requiring high efficiency and low standby power consumption.
Replacement Considerations
LT8610ABEMSE-5#PBF offers similar electrical characteristics within the same package. LT8610AIMSE-5#PBF is another compatible variant in the series. Verify pinout compatibility and thermal performance before substitution.
