Fairchild Semiconductor 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, Sales and Marketing, China and South East Asia. “The FSEZ1016A is an excellent example of the value of Fairchild’s Global Power ResourceSM (GPR). 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.”
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.
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.
