Overview
The LT8471EFE#TRPBF is a dual multitopology DC/DC converter featuring two independent 2A switches. It supports buck, boost, inverting, and SEPIC configurations with external synchronization capability. The device operates from an input voltage range of 2.7V to 36V, providing flexible power conversion for various industrial and communication applications.
Feature Summary
- Dual independent channels supporting multiple topologies including buck, boost, inverting, and SEPIC
- Integrated high-current 2A switches for efficient power handling
- External synchronization input for noise reduction and system timing alignment
Applications
- Industrial control systems requiring isolated or non-isolated dual rails
- Telecommunications equipment power distribution
- Automotive electronics with varying input voltage requirements
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official Analog Devices documentation prior to integration. Ensure component authenticity by sourcing from authorized distributors only.
Selection Notes
Select this part for designs needing two distinct regulated outputs from a single controller IC. Evaluate thermal performance based on total switch current and PCB copper area. Verify that the required topology combinations are supported by the selected external components.
Part Context
This component belongs to the LT8471 family of dual multitopology converters. It shares functional similarities with other Linear Technology dual-channel controllers but offers specific synchronization and topology flexibility not found in standard single-output regulators.
Replacement Considerations
LT8471EFE#PBF is the tube-packaged equivalent. Cross-reference with LT8471MPFE#TRPBF for military-grade temperature variants if environmental specifications require extended operating ranges.
