Fairchild Semiconductor, a provider of energy-efficient, easy-to-use and value-added semiconductor solutions for power and mobile designs, has expanded its LED lighting driver solutions portfolio to include an optimized low-power offering.

As a MOSFET technology leader, Fairchild continues to offer the latest in LED lamp drivers. The FLS0116, FLS3217 and FLS3247 with integrated MOSFET and power factor correction (PFC) are optimally designed for low-power LED applications. With the addition of the integrated power MOSFET, these devices help to minimize board space and overall component count while decreasing design time. Equipped with cycle-by-cycle current limiting and integrated protection features such as over temperature protection (OTP) and under-voltage lockout (UVLO) these devices help to significantly improve LED lamp system reliability.

The FLS0116 utilizes an “adopted digital” technique that automatically detects AC and DC input voltage conditions, enabling and disabling PFC functions while also offering programmable oscillation frequency and analog dimming and soft-start functions. The FLS3217 and FLS3247 with primary-side regulation (PSR) can support isolated flyback converter and non-isolated DC-DC converter applications. Additionally, the devices regulate accurate output current by using a  precise constant-current control (CC) function and increase efficiency for an easier design with linear frequency control.
