Voltage converting controller, voltage converting circuit, and control method for voltage converting

摘要

A voltage converting controller, in which when an 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; and after a period of time, sets the control frequency to a target control frequency corresponding to the second current value. In addition, 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, sets a steady state value of the secondary-side output voltage to an output voltage steady state value corresponding to the second current value.
