说明

AW21018 is an 18-channel multi-function LED driver. Each channel has individual 8-bit DC current setting for color-mixing and maximum 12-bit PWM resolution for brightness control. The global current of each channel is recommended to be 40mA configured via register and external resistor REXT.
Group control mode, autonomous breathing pattern and rapid RGB control mode are provided for flexible, high efficiency lighting effect programming and fast display updating.
Programmable phase-shifting and spread spectrum technology are utilized to reduce EMI and audible noise caused by MLCC when LEDs turn on in off simultaneously.
AW21018 can be turned off with minimum current consumption by pulling the EN pin low.
AW21018 is available in QFN 4mmX4mmX 0.85mm-32L package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
