NJU6063
RGB LED Controller Driver with PWM Control
■ GENERAL DESCRIPTION
The NJU6063 is RGBLEDcontroller driver with PWMcontrol.
It contains PWM controller, LED drivers, I2C interface and constant current
driver etc.and can controlRGBLED individually.
NJU6063 can reduce board density because the external parts are
unnecessaryfor it includesconstantcurrentdriver.
Making LED a polychromatic light is possible by the control of the PWM
dimming Circuit.
Also, multiple NJU6063 can be controlled bythemultidevice control.
The NJU6063 is suited for a large number of applications such as cellular
phones, car stereo sets, household appliances, illumination equipment and
gaming equipments,etc.
