AW21036C is a 36-channel high precision constant current LED driver. Each channel has individual 8-bit PWM current for brightness control. The maximum global current of each channel is recommended to be 40mA configured via external resistor REXT.
Programmable spread spectrum technology are utilized to reduce EMI and audible noise caused by MLCC when LEDs turn on or off simultaneously.
AW21036C can be turned off with minimum current consumption by either pulling the EN pin low or setting bit GCR.CHIPEN=0.
AW21036C is available in QFN 5mmX5mmX 0.75mm-44L package. It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
