Overview
The CS1610A/1A/12A/13A 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 CS1610A/11A is designed to control a quasi-resonant flyback topology. The CS1612A/13A is designed to control a buck topology. The CS1610A/12A and CS1611A/13A are designed for 120VAC and 230VAC line voltage applications, respectively.
