NJU6049 - 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.

Key Features

  • low operating voltage of 1.7V and the small package VSP10. All of these benefits make the NJU6049 suitable for the battery-powered portable.

NJU6049 www.DataSheet4U.com PRELIMINARY 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 portable applications such as cellular phones, camcorders, PDAs, etc.
