The LP5521 is a three-channel LED driver designed for mobile devices, featuring an adaptive charge pump with 1x and 1.5x gain. It includes internal program memory for autonomous operation without continuous processor control, reducing overall system power consumption. Each channel is independently programmable with 8-bit current setting and 8-bit PWM control.
