Telecommunication Infrastructure

Why Choose Fairchild Solutions

Fairchild has a broad range of signal and power management semiconductor solutions for telecommunication end systems. Communication providers have been expanding their network coverage from urban cities into rural and remote areas that lack access to reliable services. Power availability and seconds of downtime per year are measures of reliable equipment. You can find Fairchild products in telecom and broadband equipment as well as the equipment that powers those end systems. Whether converting AC or DC power into precisely-controlled DC power, our products are used in critical telecom uninterrupted power supply (UPS), solar inverter, data centers, central offices, cell towers, fiber optics gear and customer facilities for mobile internet and cloud computing applications.

Fairchild is a leading power discrete semiconductor supplier to telecommunication equipment manufacturers and designers of these systems because our solutions enable the higher power density and low power consumption demanded in telecommunications systems.
