Lumissil IS31FL3238 18-Channel LED Driver

Lumissil IS31FL3238 18-Channel LED Driver features Pulse Width Modulation (PWM) by 16-bits for smooth LED brightness control. Each channel provides an 8-bit output current control register that allows fine-tuning of the current for RGB color mixing. This LED driver offers 78mA of the maximum output current for each channel and is controlled by one 8-bit global control register. The IS31FL3238 LED driver operates at 2.7V to 5.5V V_CC supply range and -40°C to 125°C temperature range.
