Fairchild Semiconductor Releases the Industry's Smallest 5V/30mA Boost Converter

The FAN5665 Saves 20 Percent Board Space in Portable Applications

San Jose, California – December 27, 2007 – Fairchild Semiconductor (NYSE: FCS) brings designers an ultra-small boost converter solution for their space-constrained mobile and ultra-portable devices. The FAN5665 is a high efficiency 5V/30mA adaptive charge pump boost converter packaged in a low profile, compact 1.21mm X 1.21mm WL-CSP package, saving over 20 percent board space compared to alternate solutions. For USB enabled devices needing a 5V I/O rail, Fairchild’s FAN5665 provides an optimal “quick fix” solution. The FAN5665 can also be used to drive keypad LEDs in portable devices. This boost converter features a low 0.625mm (max) profile and does not require a bulky inductor, offering a slim solution for network cards or other thin portable applications.

Through the use of switch reconfiguration and fractional switching techniques, the FAN5665 achieves up to 92 percent efficiency and can support an input voltage range of 2.9V to 5.5V. In addition, the switches are pre-buffered to provide a low in-rush current which results in minimized noise on the supply line. Also, by not requiring an inductor, EMI noise is reduced, which could potentially save system designers time during the final stages of system verification.

This adaptive charge pump boost is part of Fairchild’s comprehensive portfolio of power conversion products that offer high efficiency, low power consumption and integrated functions in smaller footprints for today’s designs.

The FAN5665 utilizes lead-free (Pb-free) terminals and has been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchild's products are designed to meet the requirements of the European Union's Directive on the restriction of the use of certain substances (RoHS).
