Overview
The LT8610ABIMSE-3.3#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc., designed for high-efficiency power conversion in compact spaces. It operates with an input voltage range from 3.4 V to 42 V and delivers a fixed output of 3.3 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 exposed pad, suitable for surface mount applications across industrial and automotive temperature ranges.
Feature Summary
- Synchronous buck topology ensures high efficiency across wide load ranges
- Ultra-low quiescent current minimizes standby power consumption
- Integrated Silent Switcher technology reduces electromagnetic interference emissions
- Adjustable switching frequency allows optimization for size or performance
Applications
- Industrial equipment power distribution
- Automotive infotainment and sensor systems
- Point-of-load regulation for digital circuits
- Battery-powered portable instrumentation
Procurement Notes
Verify the complete part number including suffixes such as #PBF for lead-free compliance and IMSE for package type. Confirm RoHS status and manufacturing origin through official Analog Devices documentation. Check for recent Production Change Notices affecting assembly or sourcing. Ensure compatibility with your PCB footprint and thermal design requirements before finalizing procurement.
Selection Notes
Select this variant when a fixed 3.3 V output is required with high current capability. Consider the MSOP-16 package for space-constrained designs. Evaluate thermal performance based on expected load and ambient conditions. Compare against adjustable versions if flexible output voltages are needed later in the design cycle.
Part Context
This component belongs to the LT8610A family of micropower synchronous buck regulators. The AB designation indicates specific internal revisions or testing criteria defined by Analog Devices. It shares core architecture with other LT8610 variants but offers optimized characteristics for industrial and automotive environments. The family emphasizes low noise and high efficiency in small form factors.
Replacement Considerations
LT8610AIMSE-3.3#PBF may serve as a direct functional substitute within the same product family. Verify pinout compatibility and electrical specifications before substitution. Consult Analog Devices for approved alternates if exact matches are unavailable.
