Preliminary T6326A

Low-Dropout, Constant-Current

White LED with Channel Control

FEATURES

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.

• Up to 400mA LED Bias Current

• 3% LED Current Matching

• Simple LED Brightness Control

• Low 0.05uA Shutdown Current

• 3V to 5.5V Supply Voltage Range

• MSOP-10L Package
