Analysis Of Improved Multiphase Buck Converter, Usamah Riaz Ahmad, Scott Wu
Electrical Engineering
While the number of transistors per microprocessor is rapidly increasing, the power requirements of converters are getting more and more important. The amount of current is increasing, while at the same time the output voltage is steadily decreasing. Today’s boards are exceeding 100A, while the buck converters have their output voltage below 1 V. Due to these new power requirements, multiphase buck converters are becoming more popular. In addition, this topology is usually used with voltage regulator modules (VRM).
The TPS40090EVM-002 board was used as the original multiphase buck with an input voltage of 12 V and output voltage of …
