High Efficiency White LED Driver
! 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. All of these benefits make the NJU6049 suitable for the battery-powered...
