LTC3209EUF-2

LED Driver IC Overview

The LTC3209EUF-2#PBF is a highly integrated multidisplay LED controller manufactured by Analog Devices Inc. It features an I2C interface for control and operates within a supply voltage range of 2.9 V to 4.5 V. The device provides eight output channels with a maximum output current of 600 mA per channel, suitable for driving main and camera LEDs. It utilizes a high-efficiency, low-noise charge pump to power the LED segments. The component is housed in a 20-pin QFN package (QFN-20-EP, 4x4 mm) designed for surface mount technology.

LED Driver IC Procurement Notes

Verify the specific suffix (#PBF vs #TRPBF) to confirm tube versus tape-and-reel packaging. Confirm RoHS compliance status through official Analog Devices documentation. Check current availability as distribution may be limited or subject to factory special orders. Ensure the QFN-20-EP footprint matches your PCB design requirements.

LED Driver IC Selection Notes

Select this part when an I2C-controlled, high-current LED driver is required for camera or main flash applications. Compare against the LTC3209EUF-1#PBF variant if different internal configurations are needed. Consider the DC880A demo board for initial evaluation and circuit validation before final implementation.

LED Driver IC Part Context

The LTC3209 series includes the LTC3209-1 and LTC3209-2 variants, both serving as multidisplay LED controllers. These components are part of Analog Devices' portfolio for mobile electronics, focusing on efficient power management for high-intensity LEDs. The EUF-2 designation specifies the particular pinout and functional configuration for the 20-pin QFN package.
