Microcontroller-based peak current mode control using digital slope compensation [PDF]
IEEE Transactions on Power Electronics, 2012 Microcontroller-based peak current mode control of a buck converter is investigated. The new solution uses a discrete time controller with digital slope compensation. This is implemented using only a single-chip microcontroller to achieve desirable cycle-
