Ultra Low-Dropout , Constant-Current White LED Bias - General Description The LN5926 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. For dimming control, an enable input pin is controlled by processor GPIO output pulses for 16 level linear current. Using a low frequency PWM waveform to this enable input pin also controls the average LED current which is proportional to the PWM duty. The LN5926 is suitable for single cell Li-ion battery power device that using low forward voltage white LEDs. The white LEDs can be powered directly...
