Endlessly increasing power density requirements are a major driving force behind the continuous need to find new power supply solutions. Switching regulators are the top choice for high current applications because of their high efficiency and high performance, but high power density doesn't come for free with a switcher. Components must be carefully chosen and laid out to maximize efficiency, transient response and thermal performance. Making a high density switching power supply requires significant design and test time, or does it?
