Fairchild Semiconductor’s Synchronous Buck Converter Named to EDN’s Hot 100 Products of 2007

Fairchild Semiconductor’s (NYSE: FCS) FAN5350 has been named a Hot 100 Product of 2007 by EDN Magazine in the power semiconductors and IC category. This revolutionary 3MHz/600mA DC/DC synchronous buck converter features 16uA quiescent current, 20mV transient response and low-voltage ripple. The FAN5350 is designed to power DSP core processors, application processors and I/O interfaces, and utilizes Fairchild’s proprietary new ultra-fast architecture specifically designed to simultaneously provide industry-leading quiescent current and transient-response performance. This high-performance, compact converter enables designers to meet next-generation load requirements while preserving battery life and saving board space in cell phones, media players, GPS devices, Bluetooth headsets and other single-cell 2.7V to 5.5V lithium-ion-powered portable applications.

“Fairchild’s FAN5350 datasheet shows an input voltage or 2.7 to 5.5 volts and has a 1.82 volt fixed output,” commented Paul Rako, EDN’s technical editor, in his July 2, 2007 blog. “What is remarkable about this part is the 16 microampere quiescent current while it operates at 3 MHz. The transient response is 20mV to a 300 mA load step. It is these kind of remarkable specs that make me wonder if the analog folks are going to make life pretty difficult for the digital power crowd. In addition the part can get up to 94 percent efficiency. Some companies play a game where they spec efficiency with an inductor the size of a fist, but Fairchild mentions that you can still get over 90 percent efficiency using a 1 uH chip inductor. Bravo.”

Products selected for EDN’s annual Hot 100 Products issue are chosen by its editors from the hundreds of newsworthy items that appear in the pages of EDN in print or online. Eligible products must have appeared in EDN during the year and could have been featured in EDN’s New Products section, a feature story, or an online exclusive.

EDN Editorial Director Maury Wright stated, “Our editorial team covers new product introductions on a daily basis and we see a lot of worthy products. We look back once a year and choose the introductions that we believe will have the greatest significance to the design engineer and create the Hot 100 list.”
