GENERAL DESCRIPTION  
The SP76ꢀ8 is a linear, low-side constant-current driver designed to drive high power LEDs  
from an input voltage rail. The driver acts as a current source, ensuring constant LED current  
for a range of input voltages. The SP76ꢀ8 allows implementing the lowest cost LED driver  
for a variety of applications. Internal circuitry maintains the preset constant current output  
for a wide voltage range at the LED input. The LED current can be adjusted up to ꢀ033mA  
with an external clock applied to the CTRL pin. The built-in thermal protection automatically  
stops LED current to prevent overheating. A timeout function serves as a failsafe, shutting  
down the output for currents greater than 266mA after 4 seconds of continuous operation if  
the enable input is not cycled. The part can be shut down by using the EN pin, or sent into  
Sleep Mode holding the CTRL pin low for more than ꢀ00µS.
