LED Direct AC Drive Solutions Although lighting system developers have been moving to solid-state lighting solutions, they have needed to use expensive light engines combining LEDs with switch mode power supply (SMPS) technology. Customers want smaller and low-cost solutions that are easier to implement.Fairchild’s new LED Direct AC Drive products provide cost-effective integrated circuit solutions that enable phase-cut dimming, analog dimming and PWM dimming capabilities for smart commercial lighting applications.The FL779xx family provides solid-state lighting solutions that have smaller form factors, scalable power, high performance, and longer system lifetimes. These solutions can scale power from 12W to 120W, reducing the number of different ICs that customers need to have in their inventory. Compared to SMPS solutions, these drivers do not need magnetic components and electrolytic caps, enabling them to fit into tight spaces and increase system lifetimes. They can also be tuned for low flicker without compromise on the PF and THD performance.
