5 Channel Low Dropout Current Source LN9305 ■ General Description The LN9305 low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs.
The LN9305 uses a internal resistor to set the bias current for five LEDs, which are matched to 3%.
The LN9305's advantages over ballast resistors include much lower bias variation with supply voltage variation, significantly lower dropout voltage, and in some applications, significantly improved efficiency.
The LN9305 requires a 60mV dropout at a 20mA load on each output to match the LED brightness.
The LN9305 is suitable for single cell Li-ion battery power device that ...
