Description
The iW3612 is designed to operate from a broad input voltage range of 100VAC to 230VAC. The device provides an efficient solution for solid-state lighting for LED luminaires in the 8W to 25W range.
Incorporating Renesas' proprietary Flickerless™ technology, the iW3612 removes LED flicker and permits usage with the industry's broadest range of dimmers. Additionally, the iW3612 incorporates Renesas' proprietary PrimAccurate™ primary-side control technology, minimizing the external component count by removing the need for both the traditional optocoupler and external compensation components, reducing solution size and cost.
The iW3612 integrates an innovative over-temperature (OTP) protection 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.
