T6326A

The T6326A low-dropout bias supply for white LEDs is a high-performance alternative to the simple ballast resistors used in conventional white LED designs. The T6326A with internal channel on/off select function.The T6326A uses a single resistor to set the bias current for four LEDs, which are matched to 3%. The T6326A advantages over ballast resistors include significantly better LED to LED bias matching, much lower bias variation with supply voltage variation, significantly lower dropout voltage, and in some applications, significantly improved efficiency.The T6326A is available in MSOP-10L and SOP-16L lead-free Package package.
