Designed for portable applications in portable phones, digital still cameras, and PDAs, the STw4141 DC/DC converter chip allows two different output voltages to be generated using a single external coil. By doing so, the STw4141 allows the bill of materials for a product to be cut by up to 40 percent, while reducing printed circuit board size up to 30 percent. It also allows a power supply solution to be implemented in only 56 mm2 of printed circuit board space, compared to 80 mm2 for the best previous approaches.
