SP7616  
High Accuracy 4-Channel Low Side LED Driver for  
CCFL Replacement  
May 2009  
Rev. 2.0.4  
GENERAL DESCRIPTION  
APPLICATIONS  
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.
