The iW3614 is a high-performance AC/DC power supply controller optimized for dimmable LED luminaires requiring high Power Factor (PF). Designed to operate from a broad input voltage range of 100VAC to 230VAC, the iW3614 provides an efficient solid-state lighting solution for LED luminaires in the 3W to 15W range.
Incorporating Renesas' proprietary Flickerless™ technology, the iW3614 removes LED flicker, provides high PF (>0.9) and permits usage with the industry's broadest range of dimmers. Additionally, the iW3614 incorporates Renesas' proprietary PrimAccurate™ primary-side control technology, minimizing the external component count by removing the need for both the traditional opto-isolator and external compensation components, reducing solution size and cost.
The iW3614 integrates an innovative over-temperature protection (OTP) derating feature that uses an external NTC device to monitor the temperature of an LED luminaire. The OTP derating feature protects the LED driver circuit by reducing output current drive to the LEDs during an over-temperature event, enabling continuous light output even in an overheating situation.
