Ultra Low-Dropout, Constant-Current White LED Bias LN9358 ■ General Description The LN9358 is a high performance ultra low- dropout constant current bias supply for white LEDs. It can be used as an alternative to the simple ballast resistors in conventional parallel white LEDs applications. It’s in the voltage range of 2.5V~6V to provide a stable 11 roads 20mA current input, no external capacitance , no inductance resistors, no noise and small size. LN9358 not only provide PWM brightness control, but also provide single-wire serial mode for 16 level linear current brightness control. The LN9358 is suitable for single cell Li-ion battery power device that using low forward voltage white LEDs. The white LEDs can be powered directly from battery without extra external components.
