LT8393HUFDM#TRPBF

LED Driver IC Overview

The LT8393HUFDM#TRPBF is a synchronous four-switch buck-boost LED controller designed for high-voltage lighting applications. It supports an input voltage range of 4V to 60V and regulates output voltages up to 100V. The device integrates PWM dimming control and operates as a DC-DC controller with step-down, step-up, or buck-boost topologies. Packaged in a 28-lead WQFN (4x5mm) exposed pad, it meets AEC-Q100 automotive qualification standards.

LED Driver IC Feature Summary

• Synchronous four-switch buck-boost topology enables regulation when input voltage is above, below, or equal to output voltage
• Integrated analog and PWM dimming control capabilities for precise LED current management
• Automotive-grade reliability compliant with AEC-Q100 qualification standards

LED Driver IC Applications

• High-voltage LED lighting systems requiring buck-boost regulation
• Automotive exterior and interior LED illumination modules
• Industrial LED drivers operating with variable input supply voltages

LED Driver IC Procurement Notes

Verify the complete part number including suffix TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and specific temperature grade. Ensure compatibility with PCB footprint dimensions for the 28-WQFN package. Cross-reference thermal pad requirements for proper heat dissipation design.

LED Driver IC Selection Notes

Select this component when input voltage fluctuates significantly relative to the required LED string voltage. The synchronous buck-boost architecture eliminates the need for external diodes, improving efficiency compared to traditional boost-only or buck-only controllers. Consider the 100V maximum output capability for series-connected LED arrays.

LED Driver IC Part Context

This part belongs to the LT8393 family of synchronous buck-boost LED controllers from Analog Devices. It shares architectural similarities with other devices in the series but is distinguished by its specific automotive qualification and pinout configuration. The HUFDM suffix indicates the specific package type and reel quantity variant.

LED Driver IC Replacement Considerations

LT8393HUFDM#PBF is the tube-packaged equivalent of the same functional device. Direct substitution requires verifying that the packaging format change does not impact assembly line processes. No alternative functional equivalents are confirmed in the provided data.
