AL179x LED Drivers

The AL179x series from Diodes serves as the LED driving element along with an AC-DC power conversion block and intelligent wireless MCU for emerging smart-connected lighting system configuration. The AL179x series enables cost-effectiveness, excellent dimming performance, low-standby power, ease-of-system implementation, and great scalability. AL1791, AL1792, AL1793, and AL1794 are 1-channel, 2-channel, 3-channel, and 4-channel LED drivers, respectively. The AL179x series is available in a U-DFN4030-14 package.

Features
  • Linear constant current regulation (CCR)
  • E-flicker-free high-frequency PWM with deep dimming
  • Ratio-optimized currents for four independent LED channels (AL1794)
  • Integration of low-side current sink MOSFET
Applications
  • 1-channel dimmable smart-connected light (SCL)
  • 2-channel tunable white SCL bulbs
  • 3-channel tunable white or color SCL bulbs
  • 4-channel tunable white+color SCL bulbs
  • Smart-connected LED tubes, panel lights, troffers, and ceiling lights
