Abstract :
The dynamics is improved to approximately first order by using peak current mode control, because of reducing a system order due to the inductor current is restrained as a control signal. However, the voltage mode control is mainly used, and there are few applications for which peak current mode control is used in VRM application. This paper presents, the transient response of VRM with peak current mode control is examined analytically and experimentally
