GENERAL 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.
