Abstract
A cross regulation circuit for multiple outputs, includes an input end and at least two output ends. A first output end of the at least two output ends is connected to a feedback circuit. The feedback circuit is connected to the input end and used for maintaining the output voltage of the first output end by adjusting the input end. A first resistor and a first inductor are sequentially connected in series on the upstream of each of other output ends than the first output end and are used for performing cross regulation. In the cross regulation method of the circuit, simultaneous equations are established through parasitic inductance on any output branch and load thereof as well as parasitic inductance on the first output branch so as to obtain the inductance of the first inductor and the capacitance of the first resistor.
