Overview
The LT8610ABIMSE#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.4 V to 42 V and delivers a maximum output current of 3.5 A. The device features a fixed 5 V output and utilizes a 16-lead MSOP package with an exposed pad for thermal management. It supports adjustable switching frequencies from 200 kHz to 2.2 MHz and maintains a quiescent current of 2.5 uA. The component 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 distribution systems
- Point-of-load regulation modules
- Battery-powered equipment requiring efficient conversion
- Embedded system power supplies
Procurement Notes
Verify the specific suffix configuration against official Analog Devices documentation to ensure compatibility with required output voltage and packaging options. Confirm RoHS compliance status through the manufacturer's certified datasheet. Cross-reference the part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when a fixed 5 V output is required alongside high current capacity up to 3.5 A. Ensure the application input voltage remains within the 3.4 V to 42 V operational window. Consider the MSOP-16 package constraints for thermal dissipation and PCB layout requirements. Validate that the desired switching frequency aligns with external component selection guidelines provided in the technical data.
Part Context
This part belongs to the LT8610A series, which includes variants such as LT8610AIMSE#PBF and LT8610ABIMSE-5#PBF. The 'AB' designation typically indicates specific performance or manufacturing lot characteristics defined by the manufacturer. Related development tools include evaluation boards like DC2012A and DC2139A for circuit validation.
Replacement Considerations
LT8610ABIMSE-5#PBF provides a fixed 5 V output option within the same series. LT8610ABIMSE#TRPBF offers tape-and-reel packaging for automated assembly. LT8610AIMSE#PBF represents the standard non-'AB' variant with similar electrical specifications.
