LT3965IFE-1#TRPBF

LED Driver IC Overview

The LT3965IFE-1#TRPBF is an LED bypass switching device designed for dimming individual LEDs within a string using a common current source. It integrates eight individually addressable bypass switches, allowing precise control over specific LEDs in a matrix configuration. The device operates from an input voltage range of 8 V to 60 V and supports both I²C and PWM dimming interfaces. It features a buck or boost topology with a maximum output current capability of 500 mA per channel. Packaged in a 28-lead TSSOP with exposed pad, it functions reliably across temperatures from -40°C to +125°C.

LED Driver IC Feature Summary

• Integrates eight individually addressable bypass switches for precise LED dimming
• Supports I²C and PWM dimming interfaces for flexible control
• Operates with a common current source architecture

LED Driver IC Applications

• Matrix LED lighting systems requiring individual LED control
• Automotive interior and exterior lighting applications
• Architectural accent lighting with dynamic color or brightness adjustment

LED Driver IC Procurement Notes

Verify the exact suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official Analog Devices documentation prior to procurement. Ensure the design accommodates the 28-TSSOP-EP thermal requirements. Cross-reference the specific revision level against the latest datasheet to confirm pinout and electrical characteristics match the intended application requirements.

LED Driver IC Selection Notes

Select this component when designing LED matrices that require independent dimming of individual elements without separate drivers for each LED. It is suitable for applications needing high input voltage tolerance up to 60 V. Consider the thermal performance of the TSSOP package for high-current scenarios. Verify compatibility with existing I²C bus architectures or PWM controller outputs before finalizing the design.

LED Driver IC Part Context

This part belongs to the LT3965 family of LED bypass switches manufactured by Analog Devices. It shares functional similarities with the LT3965IFE variant but differs in packaging format. The series is designed for efficient LED management in complex lighting arrays, offering a compact solution compared to discrete switch implementations.

LED Driver IC Replacement Considerations

LT3965IFE#TRPBF is a direct alternative differing only in packaging format (tube vs. reel). LT3965IFE-1#PBF offers the same functionality in tube packaging. Verify pinout compatibility and thermal dissipation capabilities when substituting between these variants.
