The LTC3209EUF-1 from LT is a versatile LED driver IC designed for applications requiring efficient and programmable LED control. It utilizes a multi-mode charge pump topology, providing up to 94% efficiency across its 1x, 1.5x, and 2x modes. This device can deliver a total output current of up to 600mA.
The LTC3209EUF-1 features 8 distinct current sources, configured as 5 MAIN, 2 CAM, and 1 AUX, allowing for flexible illumination control. Brightness levels for the MAIN display can be set across 256 states, the CAM display has 16 states, and the AUX display has 4 states. Control and programming are managed via a 2-wire I2C interface, enabling On/Off and brightness adjustments.
Designed for low noise and constant frequency operation, the IC includes internal soft-start to limit inrush current during startup and mode switching. It also incorporates comprehensive protection features, including short circuit, thermal, and open-shorted LED protection. The device is housed in a compact 20-lead 4mm x 4mm QFN package, making it suitable for space-constrained designs like video and camera phones with QVGA+ displays.
The LTC3209EUF-1 can deliver a total output current of up to 600mA.
The input voltage range is 2.9V to 4.5V.
The operating temperature range is 0°C to 85°C.
The LTC3209EUF-1 is packaged in a 20-lead QFN package measuring 4mm x 4mm.
It can drive up to 5 main LEDs, 2 CAM LEDs, and 1 AUX LED.
The switching frequency is 850kHz.
The efficiency is up to 94% in 1x, 1.5x, and 2x gain modes.
