iW3631
Flickerless™ 0-10V Dimmable Two-Stage Digital AC/DC SSL LED Driver for Commercial Lighting up to 120W
双级Flickerless™0-10V可调光的数字离线LED驱动器，具有高PF和低THD
The iW3631 two-stage LED driver is a dimmable digital offline PWM controller for solid state lighting applications up to 120W with high power factor (PF > 0.95) and low THD (< 10%). It features a built-in driver for isolation transformers that enables direct, 0-10V dimming without the need for an external MCU and driver circuit, reducing cost and complexity. The iW3631 can also be implemented to support a PWM dimming interface to simplify use in wireless SSL applications.
The iW3631 operates in a quasi-resonant mode to provide high efficiency and uses Dialog’s PrimAccurate™ advanced primary-side sensing technology to achieve excellent line and load regulation without secondary feedback components. The digital control algorithms used by the iW3631 maintain stability over all operating conditions without the need for any external loop compensation components, minimizing the BOM cost.
The iW3631 can be paired with Dialog'sIW337.3合1调光接口。
