Abstract :
This paper presents, the availability of peak current mode control in low-voltage application is verified analytically and experimentally. As a result, in peak current mode control, it is desirable to enlarge DC gain to reduce the output impedance, and decreasing the output impedance reduces the output voltage drop. Choosing the value of the current to voltage gain kiv and the error amplifier gain K can easily reduce the voltage variation at the transient time appropriately.
