www.DataSheet4U.com Preliminary RT9269 Tiny Package, High Efficiency, Constant Current LED Driver General Description The RT9269 is a compact, high efficient LED driver with high flexibility of application configurations in charge pump mode or in boost rectifier mode, delivering Tens of mA constant output current for driving 1~4 white LED’s. The 0.25V low reference voltage minimized the power loss across the current-setting resistor. The wide applicable VDD range makes RT9269 suitable for 1 to 4 battery cell applications as well as being supplied with 2.5/3.3/5/6V system powers. The 500kHz high switching rate minimized the size of external components. Besides, the 17µA low quiescent current together with high efficiency maintains long battery lifetime.
