The MAX8648ETE+T is an ultra-efficient charge pump LED driver from Analog Devices / Maxim Integrated, capable of driving up to six white LEDs or two sets of RGB LEDs. It provides regulated constant current for display backlight and fun light applications.
Key electrical specifications include a supply voltage range of 2.7V to 5.5V, an output current of 24mA per channel, and a switching frequency of 1MHz. The device supports multi-step dimming with a range from 24mA down to 0.1mA. It also features a low quiescent current of 70µA and a shutdown current of 1µA.
Designed for high efficiency, the MAX8648ETE+T utilizes an inverting charge pump and low-dropout adaptive current regulators. It includes thermal shutdown, open- and short-circuit protection, and a temperature derating function to protect LEDs at high ambient temperatures. The device is suitable for applications such as white LED backlighting, single or dual display backlighting, and camera flash or RGB indicators.
The MAX8648ETE+T is available in a 16-pin, 3mm x 3mm thin QFN package, suitable for surface mount applications. The operating temperature range is -40°C to 85°C (TA).
