NOT RECOMMENDED FOR NEW DESIGN USE AL1783 AL1781/1782 SINGLE/DUAL DIMMABLE LINEAR LED DRIVER Description The DIODES™ AL1781/1782, a single/dual-channel dimmable Linear LED driver with PWM dimming control, is targeted for 1-Channel dimmable and 2-Channel tunable Smart Connected Lighting (SCL) applications. It serves as the LED driving element along with AC-DC Power Conversion Block and Intelligent wireless MCU as an emerging connected lighting applications. The AL1781/1782 key merits attribute to dimming performance, low standby power, ease of system implementation and great scalability. It supports High Frequency E-flicker free PWM dimming with Deep Dimming Capability: Support 40kHz down to 4%, 10kHz down to 1.0%, 4kHz down to 0.4%, or 1kHz down to 0.1% with good dimming linearity.
