CS1610/11 CS1612/13 TRIAC Dimmable LED Driver IC Features & Description Overview • 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 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
