IS32FL3202 Datasheet | Lumissil

DESCRIPTION IS32FL3202 is a three channel LED controller. Each LED channel supports 6-bit DC (Dot Correction) current adjustment for color setting and 12-bit PWM for smooth LED dimming control. The maximum output current of each LED channel (for R, G, B) is 63m A. All registers in the IS32FL3202 can be accessed via a Lumissil proprietary bus (Lumibus). IS32FL3202 supports LAA (Location Address Assignment) for random LED driver access without address pins. IS32FL3202 can measure the LED chip temperature, which is applied to the built-in temperature pensation algorithm to provide constant luminance over wide operating temperature range. After temperature pensation, final PWM data is kept to 16-bit for more precise color presentation. To minimize the EMI, IS32FL3202 supports spread spectrum in the PWM clock generator. IS32FL3202 is available in WFDFN-10 (3mm×3mm), operates from 3.5V to 6.5V over the temperature range of -40°C to +125°C.
