GENERAL DESCRIPTION
The T6316A/B low-dropout bias supply for
white LEDs is a high-performance alternative
to the simple ballast resistors used in
conventional white LED designs. The T6316A
uses a single resistor to set the bias current for
four LEDs, which are matched to 3%. The
T6316B build in internal resistor to set the bias
current for four LED. The T6316A/B
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 T6316A/B is
available in SOP-8 package and lead-free.
