  • Voltage converting controller, voltage converting circuit, and control method for voltage converting
    Patent number: 9287785
    Abstract: A voltage converting controller. When output current increases from a first current value to a second current value, the voltage converting controller temporarily sets a control frequency to a maximum frequency value. After a period of time, the voltage converting controller sets the control frequency to a target control frequency corresponding to the second current value. And, when the output current increases from the first current value to the second current value, the voltage converting controller temporarily sets a secondary-side output voltage to an transient output value; and after a period of time, the voltage converting controller sets a steady state value of the secondary-side output voltage to an output voltage steady state value corresponding to the second current value.
