NJU6052 com PRELIMINARY White LED Driver with Automatic Dimming Control ! GENERAL DESCRIPTION The NJU6052 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 60mA maximum capability which allows the connection of 12 white LEDs (4 series x 3 parallels).
Depending on the ambient light sensed with an external luminance sensor, the PWM controller controls PWM duty in 8 steps preselected out of 64 steps.
In addition, the frequency of the DC/DC converter is high so that it permits...
