0.9V-White LED Driver -Only One External Component Required

(PresseBox) (Mainz, )
The core of the new driver PR4401 consists of a step-up converter with current output, that provides an output voltage of typically 3.6V for white LEDs. The input voltage can be as low as 0.9V, thus allowing a single cell battery operation.

Only one external component, an inductor, is required to operate up to three LEDs in series. A regulated current of up to 23mA depending on the inductor value provides a constant LED brightness independent of the supply voltage. The PR4401 offers a high efficiency of about 80% over the whole supply voltage range from 0.9V up to 6B. Nlwb olk pxfcsis isegpwcp qx ikwh eznu 27 hcwit ohxm pr HQ sroexlux yiyfcys.
