Note1) All voltages are relative to VSS = 0V reference.
Note2) Do not exceed the absolute maximum ratings, otherwise the stress may cause a permanent damage to the IC. It is also recommended that the IC be used in the range specified in the DC electrical characteristics, or the electrical stress may cause mulfunctions and impact on the reliability.




Description

The NJU6050 is a high-efficiency white LED driver. It contains a high-efficiency step-up DC/DC converter and an  output driver. The IC NJU6050 ensures a 28V maximum capacity which allows series connection of 8 white LEDs with a constant current so that the LED currents are identical for uniform brightness.

The high frequency of the step-up converter NJU6050 permits the use of small, low-profile inductors and capacitors to minimize the footprint in space-conscious applications. And additional features are a low operating voltage of 2.5V and the small package SOT-23 (MTP-5).

All of these benefits make the NJU6050 suitable for the battery-powered portable applications such as a cellular phone, a camcorder, PDA, etc.
