AS68032

RGB three channel linear dimming chip

AS68032 is a high-precision 3-route LED modulation drive, which can independently set the PWM signal duty ratio of 3 channels through 3 PWM interfaces to achieve the dimming and color adjustment function.

The AS68032 uses PWM chopper square dimming, and the minimum dimming depth can reach less than 0.1%. The AS68032 has a 3-way LED channel with a voltage of 40V and a maximum current of 200mA per channel. The AS68032 has a high constant current accuracy of ±5%@20mA.

The AS68032 has an integrated overheat protection function. When the chip temperature exceeds the overtemperature protection point, the chip automatically reduces the output current to ensure system stability.
