MaxLinear, Inc. LED Drivers SP7616ER-L/TR

The SP7616ER-L/TR is a 30V, 4-channel linear LED driver designed for driving up to four LED strings, with a maximum current of 60mA per channel, allowing for a total of 36 LEDs. It features a typical current matching of 1.5% between channels, ensuring consistent color temperature across displays. The LED current can be adjusted using an external resistor, and the device supports both PWM and analog dimming methods, enabling flicker-free brightness control at frequencies up to 5 kHz with a minimum duty cycle of 10%. The driver operates within a wide input voltage range of 4.5V to 30V and has a low dropout voltage of 150mV at 20mA, which enhances system efficiency. It includes built-in thermal protection to prevent damage under fault conditions. The SP7616ER-L/TR is packaged in a compact 2x3mm DFN format and is RoHS compliant, making it suitable for various applications such as TFT display backlighting, casino gaming lights, and advertising displays.
