NJU6051  
PRELIMINARY  
White LED Driver with Automatic Dimming Control  
ꢀ PACKAGE OUTLINE  
ꢀ GENERAL DESCRIPTION  
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.  
NJU6051KM1  
The output driver ensures a 30mA maximum capability  
which allows the connection of 8 white LEDs (4 series x 2  
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 the use of small, low-profile inductors and capacitors  
to minimize the footprint in space-conscious applications.  
All of these benefits make the NJU6051 suitable for the  
battery-powered portable applications such as a cellular  
phone, a camcorder, PDA, etc.
