NJU6052

PRELIMINARY

White LED Driver with Automatic Dimming Control

ꢀ PACKAGE OUTLINE

ꢀ 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.

NJU6052KN1

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 the use of small, low-profile inductors and capacitors

to minimize the footprint in space-conscious applications.

All of these benefits make the NJU6052 suitable for the

battery-powered portable applications such as a cellular

phone, a camcorder, PDA, etc.
