A6280  
3 Bit Constant Current LED Driver with PWM Control  
Features and Benefits  
Description  
5 to 17 V operation  
TheA6280isa3bitconstantcurrentLEDdriverthathasawide  
range of output currents. The A6280 controls LED luminance  
with a pulse width modulation (PWM) scheme that gives the  
application the capability of displaying a billion colors. The  
overall maximum current is set by an external resistor.  
Wide output current range (10 to 150 mA per output)  
3×7 bit Dot Correction current settings  
31 bit shift register  
3×10 bit PWM luminance settings  
Buffered output control pins  
The LED luminance is controlled by performing PWM control  
on the outputs. The luminance data of the PWM signal for each  
LED is stored in three 10 bit registers. Each LED can be dot  
corrected by a 7 bit scalar register that scales the maximum  
current from 100% down to 36.5%. All the internal latched  
registersareloadedbya31bitserialshiftregister.Onebitisused  
to control the type of data loaded into the registers, either dot  
correction/clockdividerratioorluminancedata.Theremaining  
30 bits are used for the data. This helps reduce the pin count  
of the A6280. To further lower the A6280 pin count, the PWM  
clock and the serial bus clock share the same pin and work  
concurrently to control LED luminance and to load data.  
Up to 5 MHz serial / PWM clock frequency  
Thermal Shutdown / UVLO  
Packages: 16 pin DIP (suffix A), and  
16 pin QFN/MLP (suffix ES)  
TheA6280 is designed to minimize the number of components  
neededtodriveLEDswithlargepixelspacing.SeveralA6280s  
canbedaisychainedtogetherandcontrolledbyjustfourcontrol  
signals (Clock, Serial Data, Latch, and Output Enable). Each  
of these inputs has buffered outputs on chip.Also, the VIN pin
