Overview

The CS1610/11/12/13 is a digital control IC engineered to deliver a high-efficiency, cost-effective, flicker-free, phase-dimmable, solid-state lighting (SSL) solution for the incandescent lamp replacement market. The CS1610/11 is designed to control a quasi-resonant flyback topology. The CS1612/13 is designed to control a buck topology. The CS1610/12 and CS1611/13 are designed for 120VAC and 230VAC line voltage applications, respectively.
