4 Channel LED Driver with Digital Pulse Brightness Control" ["thumb"] => NULL ["keywords"] => NULL ["description"] => NULL ["content"] => string(2045) "
GENERAL DESCRIPTION

The BCT3364 is a high performance white LED driver. The BCT3364 uses an internal resistor to set the bias current for four LEDs, which are matched to 1.5%. The BCT3364's advantages over ballast resistors include much lower bias variation with supply voltage variation, significantly lower dropout voltage, and in some applications, significantly improved efficiency. The BCT3364 requires only a 50mV dropout voltage at a 20mA load on each output to match the LED brightness.

Users can easily configure the LED current from 1.25mA to 20mA by a serial pulse. The Dimming of white LEDs current can be achieved by applying a pulse signal to the EN pin. There are totally 16 steps of current could be set by users. Internal soft start circuitry effectively reduces the in-rush current while both start-up and mode transition.

GENERAL DESCRIPTION

The BCT3299 is a LED driver with independent 16 output channels, and the output current of each channel can be programmed to achieve 256 level, with maximum up to 30 mA.

The device is equipped with an internal program memory, which allows the operation without processor control. Each channel is independently programmed to on, off, gradually light up or down over time. In audio mode, the brightness of each channel can be proportional to the strength of the audio signal, also there will be the PWM output which sync to the audio signal. BCT3299 is designed to produce versatile lighting effects for portable devices.

Less than 2uA chip off current effective extend battery usage time, BCT3299 is lead-free environmental protection products, and the temperature range is -40 ℃ to + 85 ℃. It has QFN-24 (4 x 4 mm) package, with the thickness of 0.75 mm.

APPLICATIONS

Mobile phone

MP3/MP4/CD/Media Players

Toys
