As a leader in MOSFET technology, Fairchild Semiconductor has introduced the latest LED lighting driver. The FLS0116, FLS3217, and FLS3247 with integrated MOSFET and power factor correction (PFC) are optimized for low power LED applications. With the addition of integrated power MOSFETs, these three devices help minimize board area and overall component count while reducing design time. These devices feature cycle-by-cycle current limit and integrated protection features such as overtemperature protection (OTP) and undervoltage lockout (UVLO) to help significantly improve the reliability of LED lighting systems.
The FLS0116 utilizes "adapted digital" technology to automatically detect AC and DC input voltage conditions to enable and disable the PFC function while providing programmable oscillation frequency and analog dimming and soft-start functions. The FLS3217 and FLS3247 feature primary-side regulation (PSR) for both isolated flyback converters and non-isolated DC-DC converter applications. In addition, these devices use precision constant current control (CC) to precisely regulate the output current and increase efficiency for a simpler design with linear frequency control.
Fairchild offers a wide range of LED lighting solutions for large, medium and small power range LED lighting applications, saving space, achieving high reliability and increasing overall system efficiency. By integrating various components on a single IC, Fairchild will validate proven high-efficiency and advanced circuit topologies for 1W or higher power range lighting applications. Fairchild offers a wide range of energy-efficient topological technology solutions that enable designers to achieve high power factor and low overall harmonic distortion while meeting international energy regulations. In addition, Fairchild provides the system know-how and design tools needed to help designers bring their LED IC products to market faster.
