The NJU6061 RGB LED driver from New Japan Radio Co. Ltd includes a PWM (pulse width modulation) controller, LED drivers, oscillation circuit and 8bit serial interface.

According to the data sheet, each of the R(red), G(green) and B(blue) outputs produces 128 levels individually to enable the RGB LED to emit full color. The NJU6061 also features a programmable sweep function, which can change LED color smoothly thereby reducing CPU load.

With an operating voltage of 1.7V to 5.5V, the driver requires only four external components such as three resistors for LED current adjustment and one for oscillation, which enables the NJU6061 to save PCB space. This device is available in both FFP12-B1 and SSOP14 packaging options.

Target applications for the new LED driver include cellphones, car stereo sets, household appliances and illumination equipment.
