Power chip for 75W LED lighting
Power Integrations has introduced chips for mains-powered LED lighting up to 75W.
The single stage design has both power factor correction (PFC) and a constant current regulation, and is aimed at high-bay, car park and street lamps.
RDR-290 is 92.2% efficient when feeding a 75W load from 230Vac while meeting EN61000-3-2 class C limits. Power factor is above 0.95.
“No primary high-voltage electrolytic bulk capacitor is required, making lifetimes of 50,000 hours practical, even in challenging outdoor environments and at high ambient temperatures,” claimed the firm.
