LT3965IFE#TRPBF

LED Driver IC Overview

The LT3965IFE#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 bypass switches, allowing precise control over LED brightness without affecting the entire string. The device operates with an input voltage range of 8 V to 60 V and supports I²C and PWM dimming interfaces. It integrates a DC-DC regulator capable of step-down (buck) and step-up (boost) configurations, providing flexibility in system design. The IC is housed in a 28-TSSOP-EP package and offers a maximum output current of 500 mA per channel.

LED Driver IC Feature Summary

• Eight individually addressable bypass switches enable precise per-LED dimming control within a common current source string.
• Integrated DC-DC regulator supports both buck and boost topologies for flexible power management.
• Supports digital control via I²C interface and analog dimming through PWM signals.
• Operates across a wide input voltage range from 8 V to 60 V.

LED Driver IC Applications

• Matrix LED dimming systems
• Individual LED string dimming applications
• General LED lighting drivers requiring per-channel control

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm that the component matches the Analog Devices LT3965 series specifications. Ensure the 28-TSSOP-EP package type aligns with PCB footprint requirements. Cross-reference the datasheet for thermal pad connection guidelines. Validate supply chain authenticity through authorized distributors.

LED Driver IC Selection Notes

Select this component for applications requiring independent control of multiple LEDs within a single current string. Consider the 8-channel capacity and wide input voltage range for system compatibility. Evaluate the need for I²C or PWM dimming capabilities against control architecture constraints. Assess thermal performance requirements given the TSSOP-EP package and power dissipation characteristics.

LED Driver IC Part Context

The LT3965IFE#TRPBF belongs to the LT3965 family of LED bypass switches manufactured by Analog Devices. This series is designed for high-efficiency LED dimming applications where individual LED control is necessary. The device complements other LED driver solutions by offering a unique approach to managing LED strings with varying forward voltages.

LED Driver IC Replacement Considerations
