LT3965EFE#PBF

LED Driver IC Overview

The LT3965EFE#PBF is an LED lighting driver IC designed for matrix LED dimming applications. It features an integrated 8-switch matrix capable of driving up to 500mA per channel. The device supports both step-down (buck) and step-up (boost) DC-DC regulator topologies, allowing flexible power management for various LED configurations. Control is managed via I2C and PWM interfaces, enabling precise dimming and regulation. The component is housed in a 28-TSSOP-EP package.

LED Driver IC Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to ensure correct package type and temperature range. Confirm that the #PBF designation indicates lead-free compliance as specified in the manufacturer's ordering guide. Cross-reference the datasheet revision date to ensure compatibility with current design requirements.

LED Driver IC Selection Notes

Select this component when an 8-channel LED matrix solution is required with mixed buck-boost capabilities. Ensure the application demands I2C digital control alongside PWM dimming. Verify that the 28-TSSOP-EP package fits the PCB layout constraints and thermal management needs of the target system.

LED Driver IC Part Context
