The advent of multifunctional portable equipment demands a high quality and vivid LCD display with high resolution and full colour. A white back-light becomes necessary for the LCD panels, and thus white LED driver ICs also become essential.
NJR's white LED driver, the NJU6052, is available in a tiny surface mount package, P-CSP (24-pin, 4,5 x 4,5 x 0,86 mm). The typical forward voltage of a traditional colour LED is about 2 V at 20 mA drive current, but a white LED requires about 3,5 V at 20 mA, which cannot be driven directly from a single Li-ion battery. The NJU6052 functions as a switching regulator to drive up to four white LEDs in series with boosted voltage and constant current. In addition, it features a luminance sensor control function, which can sense surrounding light accurately through an external photo transistor, and adjust the LED's brightness with eight steps.
It has built-in temperature compensation, and operates from 3,0 to 5,5 V for step-up circuits, and 1,8 to 5,5 V for logic circuits.
