Many architectural standards for communications equipment have fixed chassis sizes and power supply budgets. As processors increase in performance, more power is used and high efficiency becomes more critical. At the same time, size constraints must be met to fit all the desired features in a small form factor. A point-of-load power solution that maintains high efficiency with a reduced size allows increased card density, and the space savings translate into product differentiation and competitiveness. At the same time, designers must quickly solve technical problems during the development phase, and a simple power solution reduces burdens and brings peace-of-mind by allowing engineers to focus on other issues. Digital designers can now implement a sophisticated point of load solution that mounts easily on the printed circuit board with very little effort.
