PRELIMINARY

High Efficiency White LED Driver

ꢀ PACKAGE OUTLINE

ꢀ GENERAL DESCRIPTION

The NJU6049 is a high-efficiency white LED driver. It

contains a high-efficiency step-up DC/DC converter and an

output driver. The IC can output max.18V and drive as many

as 4 white LEDs in series with a constant current, which

guarantees the LEDs with uniform brightness.

The high frequency of the step-up converter permits the

use of small, low-profile inductors and capacitors to

minimize the footprint in space-conscious applications. The

NJU6049 also features low operating voltage of 1.7V and the

small package VSP10.

NJU6049R

All of these benefits make the NJU6049 suitable for the

battery-powered portable applications such as cellular phones,

camcorders, PDAs, etc.
