|FL7734 PWM Controller - Fairchild's FL7734 is a highly-integrated PWM controller with advanced Primary-Side-Regulation (PSR) technique to minimize components for low-power LED lighting solutions. Using the innovative TRUECURRENT technology for tight constant-current control, it enables designs with constant-current (CC) tolerance of less than ±1% in the wide line voltage range to meet stringent LED brightness requirements. FL7734 can operate with all types of phase-cut dimmers.
|PFC Controllers - Fairchild offers crucial cost and energy saving solutions by delivering a diverse range of medium- and high-power systems.
|FHR1200 Voltage Regulator - Fairchild's FHR1200 is a high-efficiency regulator that outperforms the typical shunt regulator in applications where low operating power, wide temperature, and wide voltage range is important. The regulator also features better stability and faster response than many existing regulators. Unlike the LM431 type of part, the FHR1200 can directly drive a power supply controller, thus saving parts count and circuit complexity in many applications.
|P-Ch PowerTrench® MOSFETs - Fairchild's latest medium voltage power 100 V, 150 V PowerTrench® MOSFETs are optimized power switches combining small gate charge (QG), small reverse recovery charge (Qrr) and soft reverse recovery body diode, which contributes fast switching for synchronous rectification in AC/DC power supplies. The latest 100 V, 150 V PowerTrench® MOSFETs employ shielded-gate structure that provides charge balance. By utilizing this advanced technology, the FOM of these devices is 66 percent lower than that of previous generations.
|Power-efficient solutions for an energy-sensitive world - Fairchild is a global leader in delivering energy-efficient power analog, power discrete, and optoelectronic solutions. These products maximize energy savings in power-sensitive applications such as power adapters, power supplies, lighting applications, computers, industrial controls, home appliances, renewable energy applications, mobile devices, wearable technology and more.

More about Fairchild Semiconductor
Fairchild is a leading global provider of semiconductor technology that powers the products we use and makes them more energy-efficient. Fairchild continues to build on its rich history of innovation to address one of the greatest challenges we face today – reducing wasted energy and improving efficiency in an increasingly power-hungry world. Delivering this vision is Fairchild’s way of making the world a cleaner and a better place.
The conservation of energy and the development of energy-efficient products is a critical challenge facing the world today. Energy-efficient solutions from Fairchild play a pivotal role in answering these design issues. With advanced packaging, proprietary technologies and experience in both the design and manufacturing of power semiconductors, Fairchild’s products provide the electronics industry with innovative ways to conserve energy. Fairchild’s high-performance semiconductors optimize energy in applications such as power supplies, cloud computing, mobile, lighting, motor, renewable energy, consumer, wearables and automotive applications.
Power supplies are found in everything from cell phone chargers, to set-top boxes, to industrial control, and offer a large potential for energy savings. Fairchild’s suite of power switches, power MOSFETs, IGBTs, rectifiers, PWM ICs, PFC ICs, HVICs, optocouplers, voltage references and LDOs are instrumental in increasing efficiency, while reducing standby power, size and cost.
Mobile devices are an omnipresent aspect worldwide. Fairchild’s expertise in power, backlighting and signal conditioning allow system designers to solve their challenges of miniaturization, convergence and longer battery life. Fairchild’s IntelliMAX™ advanced load switches, µSerDes™ solutions, MicroFET™ switches, LED drivers, power regulators, MOSFETs, charge pumps, analog switches and logic translators improve energy-efficiency, extend battery life and provide greater flexibility in portable devices.
