ABSTRACT:
A switching control circuit for multi-channels and multi-phases power converter according to the present invention comprises a master control circuit and a slave control circuit. The master control circuit generates a multiplier signal in response to an input voltage and an output voltage of the power converter, and generates a first switching signal to switch a first inductor of the power converter in accordance with the multiplier signal and the first-current signal generated by a first current-sense device. The slave control circuit generates a second switching signal to switch a second inductor of the power converter in accordance with the multiplier signal, the first switching signal and a second-current signal generated by a second current-sense device. Once the power converter is at light-load, the multiplier signal is disabled to turn off the second switching signal to turn off the slave control circuit for power saving of the power converter.
