Fairchild Semiconductor Showcases LED Lighting Solutions for Low-, Mid- and High-Power Applications at LpS 2012
Demonstrations will include Fairchild’s highly integrated PFC and PWM controllers that allow designers to reduce bill-of-material (BOM) count, enable smaller lamp sizes, eliminate design complexity and improve overall lighting efficiency.
Fairchild experts will be focused on LED driver applications in booth C11 with demos including:
- 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-dimming applications. The FL7730 is an active PFC controller for single-stage flyback topology designs and implemented with Fairchild’s unique analog sensing technology, the device can achieve TRIAC dimming control without flicker over the full range of 0 to 100 percent light output.
- The FL7701 smart non-isolated buck LED driver with PFC uses a digital technique that allows it to automatically detect the AC input voltage condition, allowing it to create a special internal reference signal that results in high power factor correction. The device will also work from a DC input voltage condition, automatically sensing AC versus DC input voltage conditions. The traditional technique of using a transformer in an MR application incurs additional losses with the transformer conversion; this traditional inefficient method can now be replaced using the FL7701 connected directly to a DC or AC off-line input.
- The FLS0116, FLS3217 and FLS3247 with integrated MOSFET and PFC are optimally designed for low-power LED applications. With the addition of the integrated power MOSFET, these devices help to minimize board space and overall component count while decreasing design time. Equipped with cycle-by-cycle current limiting and integrated protection features such as over temperature protection (OTP) and under-voltage lockout (UVLO) these devices help to significantly improve LED lamp system reliability.
