The AL1794, a quad-channel LED driver with analog and PWM dimming control, is targeted for Tunable White/Color Smart Lighting application. It serves as the LED driving element along with AC-DC Power Conversion Block and Intelligent MCU as emerging smart light bulb configuration. The key merits attribute to cost-effectiveness, dimming performance, low standby power, ease of system implementation, and great scalability.
