Preliminary T6326A
Low-Dropout, Constant-Current
White LED with Channel Control
GRNERAL DESCRIPTION
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
package.
