iW3605数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

The iW3605 single-stage, 25W LED driver operates without the need for a bleeder circuit while maintaining broad dimmer compatibility, providing a cost-optimized solution with a high power factor (>0.92) and low THD (<20%).

The iW3605 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 iW3605 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.
