Abstract

DC/DC converter is widely used in many electronic application power supplies. Usually, in the previously DC/DC converter control modulation, the duty cycle can be changed according the feedback signal in pulse width modulation (PWM) or the frequency be changed with a constant ON time or OFF time in pulse frequency modulation (PFM). A self-adaptive DC/DC converter control modulation is proposed in this paper. Based on the outputs of two uniform operational transconductance amplifiers which are influenced by the feedback voltage, both of the pulse ON time and pulse OFF time will be changed simultaneously. A self-adaptive frequency can be achieved in this control modulation. It can get a same output voltage ripple with a lower control frequency.
