LT3756EUD-2#TRPBF

LED Driver IC Overview

The LT3756EUD-2#TRPBF is a DC/DC controller designed for LED lighting applications, manufactured by Analog Devices Inc. It supports input voltages from 6V to 100V and can drive outputs up to 100V. The device operates at switching frequencies between 100kHz and 1MHz. It features analog and PWM dimming capabilities and includes open LED protection. The component is housed in a 16-QFN package and is rated for operation within a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Supports multiple topologies including Boost, Buck, Flyback, and SEPIC configurations
• Enables precise current regulation with integrated analog and PWM dimming controls
• Provides circuit protection through built-in open LED detection mechanisms

LED Driver IC Applications

• High-power LED lighting systems requiring wide input voltage ranges
• Automotive headlamp drivers utilizing boost or buck-boost architectures
• Industrial illumination fixtures compatible with flyback or SEPIC converters

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the manufacturer designation remains Analog Devices Inc., as Linear Technology was acquired. Ensure the QFN-16 package variant matches the required PCB footprint dimensions. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

LED Driver IC Selection Notes

Select this controller when designing circuits that demand high input voltage tolerance up to 100V. Consider the external switch requirement as the device functions strictly as a controller without internal power switches. Evaluate thermal management needs given the 125°C maximum junction temperature rating. Assess compatibility with desired dimming protocols before finalizing the design architecture.

LED Driver IC Part Context

This component belongs to the LT3756 family of LED controllers, which are engineered for versatile power conversion tasks. The EUD-2 variant specifically denotes the QFN-16 package configuration. It serves as a core control element in complex LED driver designs where flexibility in topology selection is critical for optimizing efficiency and performance across varying load conditions.

LED Driver IC Replacement Considerations

LT3756EMSE-2#TRPBF offers identical electrical specifications but utilizes an MSOP-16 package instead of QFN-16.
