SINGLE-STAGE PFC PRIMARY SIDE REGULATION LED DRIVERS Simplify Design Complexity in LED Lighting Applications Implementing dimming capabilities in a conventional TRIAC dimmer infrastructure is challenging because of compatibility issues. Additionally, small space requirements remain a consideration in ≤20W LED lighting applications. To address these obstacles, Fairchild developed the FL7730 single-stage primary side regulation (PSR) controller with power factor correction (PFC), TRIAC and analog dimming compatibility, as well as the FL7732 for non-dimmable applications. To improve power factor (≥0.9) and THD (Class-C), both devices feature constant on-time control with an internal error amplifier and low bandwidth compensator. Precise Constant Current accuracy/control (±5%) regulates accurate output current, independent of input and output voltage, allowing designers to achieve high and improved lighting quality. Advantages
- Excellent PF (≥0.9)
- Low THD (Class-C)
- Power efficiency ≥85%
- Minimizes BOM for smaller lamp size
- Accurate Constant Current (CC) control, independent online voltage, output voltage and magnetizing inductance variation
- Linear frequency control for better efficiency and simple design
- Open-LED protection
- Short-LED protection

Achieve Loud and Clear Sound While Extending Battery Life Customer demand is driving the need for louder and clearer speaker sound in mobile devices. While minimizing impact on battery life, designers can achieve the performance they require with Fairchild’s FAB3103. The 2.3W Class-D audio amplifier with integrated boost regulator and battery automatic gain control (AGC) allows for high audio output power over a power supply range of 2.5V to 5.2V from a 3.6V Li-Ion battery. At low power output, the device’s boost regulator automatically shuts down for greater efficiency and lower quiescent current consumption, resulting in longer battery runtime. The FAB3103 audio amplifier also features battery AGC that reduces gain when the power supply voltage is low in order to limit maximum power consumption, reducing distortion and preventing early device software shutdown. Available in a 12-bump, WLCSP, the FAB3103 device also offers several protection features including short circuit protection, low voltage shutdown, and click-and-pop suppression. Advantages
- Low EMI design allows filterless operation
- High noise rejection using differential audio inputs
- High efficiency boost regulator provides higher output power over battery voltages
- Boost shutdown at lower output power increases efficiency and reduces quiescent current consumption
- AGC monitors battery voltage and dynamically adjusts gain, extending battery runtime

Challenges Facing Solar Power Generation Higher cell efficiency, lower system costs, reliability and geopolitical systems all pose challenges to this market’s growth. The cost of a solar electric system is represented as dollar/watt. The current cost of a utility based solar electric system is $3.3/W (Source: DOE). Government programs are funding research to help drive down the cost to $1/W to help this market expansion. The different cost components that make up this system cost are provided in figure below. The panels represent more than 50% of the system cost; the balance of system (BOS) represents 43% and solar inverters represent 6%. In order to reach the aggressive $1/W target, advancement in all PV system components is compulsory. Power electronics, while a small portion of the total cost, will drive harvesting efficiency and therefore is critical. Panel manufacturers have made significant progress in cost reductions through new manufacturing processes and improvements in the conversion efficiencies of the solar cells. As the panel costs drop further in the future, the BOS and Solar Inverter costs will become a dominant part of the total system cost. Component Choices for Efficient, Cost-Effective and Reliable Implementations Regardless of which topology is used, designers must make careful choices when selecting the individual components. The necessary improvements in performance, cost, reliability and efficiency require special attention to the following factors and their ultimate impact on the overall system: Component count: cost, size, total power dissipation, reliability Heat/thermal management: reliability, size/weight, cost Minimization of losses and parasitics: system performance, total power dissipation Fairchild is committed to the development of components that will help designers implement systems optimized for these three important factors. Key building blocks for future harvesting and conversion implementations include:
- IGBTs, and high- and mid-voltage MOSFETs (high-voltage includes SuperFET®, SuperFET® II and SupreMOS® MOSFETs; mid-voltage MOSFETs incorporate PowerT rench® technology). These products feature high current handling capability and low conduction and switching loss.
- Gate drivers, with a wide range of options that include optically isolated; high-speed low side; and high-voltage.
- Bypass and blocking diodes that maximize energy prevent energy loss in storage systems.
- High-voltage silicon carbide (SiC) devices that offer significant improvement on both cost and efficiency in energy conversion systems as well as higher reliability.
