PowerMOS devices play a major role in a variety of power converter and control circuits. Some examples of their applications include PMICs, or boost and buck converters. Often these are used in mobile and IoT devices to convert battery voltages to circuit operating voltages.
Due to their size and internal complexity PowerMOS … Read More
The symbol for a PowerMOS device in a converter circuit schematic looks simple enough. However, it belies a great deal of hidden complexity. A single device is actually a huge array of parallel intrinsic devices connected together to act as a single high power device. While their gate lengths are small, as with many other MOS devices,… Read More
Power device designers know that when they see a deceptively simple pair of PowerMOS device symbols in the output stage of a power converter circuit schematic, they are actually looking at a massively complex network of silicon and metal interconnect. The corresponding physical devices can have a total device W on the order of … Read More
DC converter circuit efficiency can have a big effect on the battery life of mobile devices. It also can affect power efficiency for wall-power operated circuits. Even before parasitics are factored in, converter circuit designers have a lot of issues to contend with. Optimizing circuit operation is essential for giving consumers… Read More
