AW21024QNR

AW21024 is a 24-channelhigh precision constantcurrent LED driver.Each channel has individual 8-bit DC current setting for color-mixing and 8-bit PWM currentfor brightness control. The maximum global current of each channel is recommended to be 50mA configured viaregister GCCR and external Resistor REXT.

Groupcontrol mode, autonomous breathing pattern and rapid RGB control mode are provided for flexible, high efficiency lightingeffect programming and fast display updating. Programmable phase-shifting and spread spectrum technology are utilizedto reduce EMI and audible noise caused by MLCC when LEDs turn on or off simultaneously.

AW21024 can be turned off with minimum current consumption by either pulling the EN pin low or using the software shutdown feature. 

AW21024 is available in QFN 4mm×4mm×0.85mm-32L package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
