LTC3209EUF-1#PBF

LED Driver IC Overview

The LTC3209EUF-1#PBF is an LED driver IC featuring eight non-isolated outputs. It utilizes a switched capacitor charge pump topology to regulate current, supporting a total output capability of 600mA. The device operates within an input voltage range of 2.9V to 4.5V and supports I2C dimming control. It is housed in a 20-QFN (4x4) package.

LED Driver IC Feature Summary

• Integrates high-efficiency, low-noise charge pump for power delivery
• Supports I2C interface for digital dimming control
• Provides eight regulated LED output channels

LED Driver IC Applications

• Multidisplay LED controller systems
• LED lighting applications requiring multiple channels
• Indicator circuits with regulated current requirements

LED Driver IC Procurement Notes

Verify the specific suffix #PBF indicates lead-free and RoHS compliance status. Confirm the package type matches the required 20-QFN footprint for PCB layout. Ensure the I2C address configuration aligns with system bus constraints before procurement.

LED Driver IC Selection Notes

Select this component when eight isolated or non-isolated LED channels are required from a single IC. The I2C dimming feature is suitable for systems needing precise digital control. Consider the 600mA total current limit and 2.9V to 4.5V input range against load requirements.

LED Driver IC Part Context

This part belongs to the LTC3209 family of highly integrated multidisplay LED controllers. It shares architectural similarities with the LTC3207 and LTC3209-2 variants but differs in output count and control interface specifications. The DC881A serves as an evaluation board for the related LTC3209-1 device.

LED Driver IC Replacement Considerations

The LTC3209EUF-2#PBF is a related variant within the same family. Verify if the alternative requires different control logic or exhibits distinct electrical characteristics compared to the -1 suffix version.
