NJU6050 - JRC

NJU6050 High Efficiency White LED Driver

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 can output max.28V and drive as many as 8 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 induc.

Features

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 cellular phones, camcorders, PDAs, etc. ¢ PACKAGE OUTLINE ¢ FEATURES ˜ Drives Up to 8 White LEDs in Series ˜ ˜ ˜ ˜ VSW = 28V, IOUT = 20mA Uses Small Inductor and Capacitors 2.5V to 6.5V Operating Voltage for Step-up Circuits (VDD ) CMOS Technology Package : SOT-23 5 pin (MTP-5) ¢ PIN CONFIGURATION (TOP VIEW) SW VSS FB 1 2 3 5 VDD 4 SHDNb Ver.2006-03-28 -1- NJU6050 www.DataSheet4U.com ¢ PIN DESCRIPTIONS No. 1 2 3 4.
