Fairchild’s Offering

Fairchild Semiconductor provides solutions for all lighting applications including linear fluorescent ballast, compact fluorescent ballast, HID and in particular, LED lighting applications. Our extensive product portfolio ranges from discrete to integrated solutions that contain PFC controllers, primary-side regulation (PSR) PWM controllers that eliminate the secondary side control circuit; quasi-resonant converters that provide higher efficiency and reliability; high voltage gate drivers and MOSFETs. With our commitment to energy savings and meeting the most stringent regulations, we have developed innovative products that maximize performance while reducing board space, design complexity and system costs.

Saving our world, 1mW at a time™
