LT3965EFE-1#TRPBF

LED Driver IC Overview

The LT3965EFE-1#TRPBF is an LED bypass switching device designed for dimming individual LEDs within a string using a common current source. It features eight individually addressable channels and operates from an input voltage range of 8 V to 60 V. The device supports both step-down (buck) and step-up (boost) topologies, enabling flexible circuit configurations. It integrates I²C and PWM dimming capabilities for precise control. The component is housed in a TSSOP-28 package and is rated for operation between -40°C and +125°C.

LED Driver IC Feature Summary

• Eight individually addressable bypass switches for per-LED dimming
• Supports buck and boost topologies for flexible string configurations
• Integrates I²C and PWM interfaces for digital and analog dimming control

LED Driver IC Applications

• Matrix LED lighting systems requiring individual channel control
• Automotive interior and exterior lighting applications
• Architectural accent lighting with high dynamic range requirements

LED Driver IC Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm that the -1 variant matches the required pinout or functional configuration compared to the standard LT3965. Ensure the supplier provides official Analog Devices documentation to validate authenticity and revision status before integration into production designs.

LED Driver IC Selection Notes

Select this component when designing systems that require independent dimming of multiple LEDs driven by a single constant current source. The choice depends on the need for buck/boost flexibility and digital I²C control. Evaluate thermal performance within the TSSOP-28 package against the expected power dissipation of the bypass switches during operation.

LED Driver IC Part Context

This part belongs to the LT3965 family of LED bypass drivers manufactured by Analog Devices. The series is engineered for high-efficiency LED management in complex lighting arrays. The LT3965EFE-1#TRPBF specifically denotes the industrial temperature grade version in a reel format, distinguishing it from commercial grades or tube-packaged variants.

LED Driver IC Replacement Considerations

LT3965EFE#TRPBF serves as a direct substitute if the -1 variant distinction is not critical for the specific application logic.
