LT3965EFE#TRPBF

LED Driver IC Overview

The LT3965EFE#TRPBF is an LED bypass switching device designed for dimming individual LEDs in a string using a common current source. It features eight individually addressable switches and operates with an input voltage range of 8 V to 60 V. The device supports I2C and PWM dimming interfaces, offering digital programmable 256:1 PWM dimming resolution. It integrates step-down (buck) and step-up (boost) DC-DC regulator topologies to manage LED strings efficiently. The component is housed in a 28-TSSOP-EP package and includes open LED protection features.

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the -EFE variant corresponds to the specified temperature range and package type. Ensure compatibility with I2C bus requirements and check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

LED Driver IC Selection Notes

Select this component for designs requiring independent control of multiple LEDs within a single string. Consider the 8 V to 60 V input range for various supply voltages. Evaluate the thermal performance of the 28-TSSOP-EP package against system heat dissipation capabilities. Verify that the 500 mA output current capability meets the load requirements.

LED Driver IC Part Context

This part belongs to the LT3965 family from Analog Devices, specialized as an LED bypass switching device. It is distinct from standard LED drivers by its ability to bypass individual LEDs in a series string. The family includes variants like LT3965IFE and LT3965EFE, differing primarily in package and temperature specifications.

LED Driver IC Replacement Considerations

LT3965EFE-1#TRPBF is a related variant within the same family. Verify if the -1 suffix denotes a specific functional difference or pinout variation required for the design. Cross-reference datasheets to ensure compatibility with existing circuit topology.
