DESCRIPTION  
The SP7616 is a 30V 4-Channel linear low side LED driver. It is capable of powering up to four  
LED strings of nine LEDs @ 60mA per string for a total of 36 LEDs with 1.5% typical current  
matching between channels. The desired LED current can be adjusted with an external resistor,  
and the precision string-to-string current matching ensures consistent color temperature across  
the whole display. The device also features very low dropout voltage to maximize system  
efficiency and avoid difficult thermal design constraints. Dimming can be achieved by feeding a  
PWM signal to the PWM pin, or use an analog signal to control the ISET current, this allows  
brightness control without unwanted color shifts. Fast LED current turn-on/off time allows up to 5  
kHz PWM dimming frequencies with as low as 10% duty cycle, completely eliminating flicker. The  
built-in thermal protection prevents damage to the device under fault conditions.
