Cirrus Logic CS1630 and CS1631 digital LED controllers are high-performance offline AC/DC drivers for dimmable and high color rendering index (CRI) LED replacement lamps and luminaires. CS1630 and CS1631 feature Cirrus Logic's TruDim™ proprietary digital dimmer compatibility control technology and digital correlated color temperature (CCT) control system that enables two-channel LED color mixing. CS1630 LED driver is designed for 120VAC line voltage applications, while the CS1631 is optimized for 230VAC line voltage applications. These Cirrus Logic devices offer up to 30 percent higher lumens per watt compared to single-channel drivers while providing improved color temperature quality. The devices provide near-100-percent TRIAC dimmer compatibility.
