iW3631 Two-Stage, Flickerless™ 0-10V Dimmable Digital Off-Line LED Driver with High PF and Low THD 1 Description The iW3631 is a two-stage, high-performance AC/DC offline power supply controller for dimmable LED luminaires with an analog dimming interface. It controls the LED current based on an analog input voltage on the dimming pin. It has a built-in 0-10V dimming interface that works directly with 0-10V dimming systems, eliminating the need for a driver circuit and microcontroller. It can also be implemented to support wireless SSL applications without the need for auxiliary power supplies. The iW3631 uses Dialog’s unique digital FlickerlessTM technology to virtually eliminate all flicker in the entire dimming range and to minimize low frequency output ripple current.
