AL1791AFE-13

AL1791AFE-13 is a single channel current-ratio-optimized LED driver with analogue and PWM dimming control is targeted for tunable white/colour smart lighting application. It serves as the LED driving element along with AC-DC power conversion block and intelligent wireless MCU as an emerging smart-connected lighting system configuration. The key merits attribute to cost-effectiveness, dimming performance, low standby power, ease of system implementation, and great scalability. Typical applications include 1-channel dimmable Smart Connected Light (SCL) bulbs and smart connected LED tubes, panel lights, troffers and ceiling lights.
