Learn how new LinkSwitch ICs deliver flicker-free TRIAC dimming in solid-state lighting applications. Power Integrations’ new LinkSwitch-PH (optimized for isolated systems) and LinkSwitch-PL (optimized for non-isolated systems) ICs are ideal for a wide range of applications including space-constrained LED driver designs, replacement lamps, and external LED ballasts (e.g., downlighting, architectural lighting, signage, and outdoor lighting). Key features and benefits include flicker-free TRIAC dimming (compatible with installed dimmers), single-stage power factor correction with constant current output (reduces system BOM and improves system reliability), and an integrated controller and high-voltage MOSFET (eliminates electrolytic bulk capacitor and optocoupler).
