Low Power LED LIGHTING SOLUTIONS Mid Power High Power The right topology, solutions and support for your design success.

Today's LED lighting applications present a complex design challenge. Requirements such as input and output voltage- current parameters; safety and power efficiency regulations; thermal performance that can improve reliability and system lifetime; limited PCB space; and the need to meet time-to-market deadlines must be addressed simultaneously. Further, the range of power topology choices forces designers to manage a more complex supply chain. To address these issues, Fairchild offers a total solution portfolio for low- (<20W), mid- (20W to 50W) and high- (>50W) LED driver applications. Our highly...

PSR PFC FLYBACK SOLUTIONS FOR LOW POWER (<20W For low-power applications, the major challenges include space and cost restrictions as well as the need to improve light radiation and conserve energy. Our primary side, regulated PWM controllers—such as the FL7730 and FL7732—have been engineered to deliver superior light quality, greater operating efficiency, and significant size and cost savings. Each controller features a multi-chip package with MOSFET built in, as well as our TRUECURRENT™ and proprietary linear predict method technologies. Together, they deliver best-in-class constant current...

CRM PFC SINGLE STAGE FLYBACK SOLUTIONS FOR MID POWER [<50W For mid-power applications such as down lights and L-Lights, designs typically start with a requirement for high PF, reduced board space, and the ever-increasing demand for greater energy savings. Fairchild's CRM PFC PWM Fairchild's LED solutions deliver the PF performance that energy regulations require, while eliminating multiple components and the performance limitations of older topologies. Design advantages include: • High PF (>0.9) with low THD for higher • No electrolytic capacitor needed • No input voltage sensing • Advanced current...

CRM PFC + QR FLYBACK SOLUTIONS FOR HIGH POWER i>50W When designing for street light, wall washing and industrial light applications, the major concerns are high system efficiency, reliability, as well as containing the BOM count and cost. By combining Fairchild's PWM controllers—such as the FL6961 or FL7930B/C—with our QR flyback technology, such as the FL6300A—you have an ideal design solution for high-power applications. Our QR controllers provide higher efficiency through extended valley switching while further reducing space by integrating SenseFET or MOSFET functionality inside. Furthermore,...

CRM PFC + LLC HALF-BRIDGE SOLUTIONS FOR HIGH POWER i>50W For LED designs in the higher power range, the BOM count, cost and efficiency continue to be a challenge. But often design complexity and system reliability are pressing issues as well. Fairchild has leveraged our extensive power supply IP for a combined CRM PFC and LLC half-bridge topology that meets these design challenges. Our FLS-xxxxXS series of controllers combines a PWM, for half-bridge resonant converters, with two highly integrated power switches, optimized for half-bridge LLC control into a single package. When used in conjunction...
