A design of rectangular wave delta modulation buck regulator

This paper describes design of rectangular wave delta modulation (RWDM) buck regulator. It has simple and compact structure, then consuming less chip area. Hence, it is suitable for implementation in portable applications. Variable frequency operation is used to obtain low loss. The proposed regulator was implemented on a breadboard to verify the concept. It shows very fast transient response. The proposed buck regulator can easily be implemented with off-the-shelf devices or integrated onto a monolithic chip.
