NJU6051 Overview
The NJU6051 is a white LED driver with an automatic dimming control. It contains an output driver, a PWM controller, a luminance sensor control (power supply for sensor & A/D converter), a step-up DC/DC converter, a serial interface, etc. The output driver ensures a 30mA maximum capability which allows the connection of 8 white LEDs (4 series x 2 parallels).
