The LP5868T is a high-current and high-performance LED matrix driver. The device integrates 18 constant current sinks with N (N = 6/8/11) switching MOSFETs to support . The LP5868T integrates 8 MOSFETs for up to 144 LED dots or 48 RGB LEDs. The LP5868T supports both analog dimming and PWM dimming methods.
