Operating frequency is proportionally adjusted by output voltage in both devices to guarantee DCM operation with optimized PF/THD and simpler design. Excellent PF (?0.9), low total harmonic distortion (THD) (Class C) and power efficiency of up to 85 percent for the FL7730 – greater than 85 percent for the FL7732 in non-dimming applications – allows these devices to meet worldwide energy saving regulations.
Fairchild offers a total solution portfolio for low- (<20W), mid- (20W to 50W) and high- (>50W) LED driver applications. Our highly integrated PWM and PFC controller solutions reduce component BOM counts to enable smaller lamp sizes and eliminate design complexities, while improving overall lighting efficiency. Fairchild’s extensive product portfolio ranges from discrete devices to integrated solutions that contain PFC controllers, high voltage gate drivers and MOSFETs. With a commitment to energy savings and meeting the most stringent regulations, Fairchild has developed innovative products that maximize performance while reducing board space, design complexity and system costs. In addition, Fairchild’s Global Power ResourceSM Center comprised of online tools, FAEs and regional centers staffed by power engineers, is the industry standard for customer design support.
