Fairchild Semiconductor's New Energy-Efficient LED Driver Lights the Way at OSRAM®

China team develops the FSEZ1016A LED driver for lighting manufacturers

Fairchild Semiconductor, a leading global supplier of high performance products that enable energy-efficiency, has been selected by one of the world’s largest lighting manufacturers, OSRAM®, to supply LED driver solutions. The FSEZ1016A was developed by Fairchild to meet and exceed the stringent performance benchmarks set by OSRAM.

“We worked closely with OSRAM’s engineers, based at the company’s LED R&D facilities in China, and frequently discussed the technical details with OSRAM in our efforts to ensure that the FSEZ1016A was the industry’s leading LED driver solution,” said Benjamin Tan, Fairchild’s regional vice president of Sales and Marketing, China and South East Asia.

“The FSEZ1016A is an excellent example of the value of Fairchild’s Global Power ResourceSM (GPR),” continued Tan. “We use regional centers staffed by power engineers and FAEs, who are tasked with providing on-the-spot design assistance. Our GPRs are widely recognized as the industry standard for customer design support.” 

Fairchild’s FSEZ1016A fits OSRAM’s 1W-4W LED products. OSRAM is also considering deploying Fairchild’s FAN6300 LED driver for its 12W to 60W products. The new FSEZ1016A and FAN6300 are designed for lighting manufacturers seeking energy-efficient LED driver solutions.

Lighting applications consume nearly 22 percent of electrical energy generated worldwide. Reducing wasted energy in these applications can have a significant impact on energy conservation. As the industry moves from standard incandescent light bulbs to CFL, LFL and LED lighting, a 75 percent energy saving can be realized. Fairchild provides solutions for all lighting applications including linear fluorescent ballast, compact fluorescent ballast, LED and HID. The company’s extensive product portfolio ranges from discrete to integrated solutions that contain PFC controllers, ballast control ICs, high voltage gate drivers and MOSFETs.

“We look forward to continuing our strategic partnership with OSRAM and to assisting them with developing and supplying further innovative devices that benefit consumers as well as the environment,” commented Tan. “Fairchild is committed to developing products that further enable energy-efficiency gains and maximize performance while reducing board space, design complexity and system costs for our customers.”

About FSEZ1016A:The FSEZ1016A is a primary side regulation (PSR) pulse-width modulation (PWM) controller, addressing a critical need in the high brightness (HB) light emitting diodes (LED) market by simplifying design, reducing board space and providing important performance advantages. The FSEZ1016A is an EZSWITCH™ device that integrates a PSR PWM controller with a power MOSFET. Through this integration, this controller achieves the most accurate constant current (CC) through built-in proprietary TRUECURRENT™ technology and tight constant voltage (CV) without using secondary-side feedback circuitry. By tightening the constant current over a wide voltage range, the same circuit can accommodate different numbers of LED units in a string, increasing design flexibility, accelerating time-to-market and stretching the lifetime of HB LEDs. With this high level of integration, this PSR PWM controller conserves board space, accommodating the form factor of lamp cases that continue to diminish in size.

To minimize the standby power consumption, the proprietary green-mode function provides off-time modulation to linearly decrease PWM frequency under light-load conditions. This green mode function assists the power supply in meeting power conservation requirements.
