iW3658 Description
The iW3658 is a highly integrated, high-performance off-line power supply controller for phase-cut dimmable LED luminaires. It uses patented PrimAccurate™ primary-side sensing technology to regulate output current accurately without the need for a feedback circuit. The iW3658 operates at boundary conduction mode to achieve high efficiency and low EMI.
