DC1039A-A

DC1039A-A demonstration circuit is a 600mA universal MultiOutput LED/CAM driver with six white LEDs, two RGB LEDs, and a camera flash featuring the LTC3207. The LTC3207 is a low noise charge pump designed to drive 12 universal LED (ULED) current sources and one high current camera flash. The LTC3207 requires only five small ceramic capacitors to form a complete LED power supply and current controller. The maximum display currents are set with an internal precision current reference. On/Off blinking, gradation, and intensity are achieved via an I2C serial interface. The part powers up in 1x mode and will automatically switch to boost mode whenever any enabled LED current source begins to drop out. The first dropout switches the part to 1.5x mode and a subsequent dropout switches the part into 2x mode. The part resets to 1x mode whenever a data byte is updated via the I2C port.

• 64 dimming states available for universal LEDs and 16 dimming states for camera LED current sources

Avisos

Do not look directly at operating LED. This circuit produces light that can damage eyes.
