CS1610/11/12/13

Dimmable LED Driver ICs

The CS1610/11/12/13 driver ICs are engineered to deliver a dimmable, high-efficiency lighting solution for the incandescent lamp replacement market. The CS1610/11/12/13 integrate a boost converter that provides power factor correction and dimmer compatibility with a constant output current second stage. Adaptive dimmer compatibility algorithms control the boost stage and dimmer compatibility operation mode to enable smooth flicker-free dimming across a zero-100% dimming range with leading-edge, trailing-edge and "smart" digital dimmers. The CS1610/11 is designed to control a flyback topology while the CS1612/13 is designed to control a buck topology.
