Dimmable Single-Stage Digital LED Driver for 45W SSL Bulb Applications

The iW3600 is a single-stage 45W LED driver that addresses dimming performance, heat and cost in high power, dimmable Solid-State Lighting (SSL) applications. It seamlessly dims from 100% down to 1% of measured light with virtually no dead travel and offers low pop-on current to enable light output at very low dimmer levels (<5% of light output), replicating the smooth, natural dimming of incandescent lighting.

The iW3600 integrates Renesas' patented intelligent dimming control to provide compatibility with a wider range of dimmers, including TRIAC, digital and universal dimmers. This technology uses digital analytics to query the dimmer and applies algorithms that automatically adapt to the dimmer type.

The iW3600 is fully protected, including Renesas' patented configurable over-temperature protection (OTP) derating. This OTP feature protects the entire LED driver circuit from excessive heating while enabling continuous light output even under high ambient temperatures often found in low airflow bulb installations.
