Cirrus公司的CS1610/11/12/13是数字控制集成电路,集成了临界导通模式(CRM)升压转换器,可提恭PFC和调光功能,恒定输出电流,效率高达90%,无闪烁调光,和IEC-61000-3-2兼容.CS1610/11用在控制准谐振反激拓扑,CS1612/13用于控制降压拓扑,CS1610/12用于120VAC电压,CS1611/13用于230VAC电压,主要用于可调光LED装饰灯,可调光LED照明,离线LED驱动器和商业照明.本文介绍了CS1610/11/12/13主要特性,方框图,典型应用电路以及典型反激电路图和降压电路图,以及CRD 1611-8W和CRD 1610-8W参考设计主要特性和指标. 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. The CS1610/11/12/13 integrates a critical conduction mode (CRM) boost converter that provides power factor correction and dimmer compatibility with a constant output current, quasiresonant second stage. An adaptive dimmer compatibility algorithm controls the boost stage and dimmer compatibility operation mode to enable flicker-free operation to <2% output current with leading-edge, trailing-edge, and digital dimmers (dimmers with an integrated power supply). CS1610/11/12/13主要特性: • Best-in-Class Dimmer Compatibility - Leading-edge (TRIAC) Dimmers - Trailing-edge Dimmers - Digital Dimmers (with Integrated Power Supply) • Up to 90% Efficiency • Flicker-free Dimming • 0% Minimum Dimming Level • Quasi-resonant Second Stage with Constant-current Output Flyback and Buck • Fast Startup • Tight LED Current Regulation: Better than ±5% • Primary-side Regulation (PSR) • >0.9 Power Factor • IEC-61000-3-2 Compliant • Soft Start • Protections: - Output Open/Short - Current-sense Resistor Open/Short - External Overtemperature Using NTC CS1610/11/12/13应用: • Dimmable Retrofit LED Lamps • Dimmable LED Luminaries • Offline LED Drivers • Commercial Lighting
