Abstract: PROBLEM TO BE SOLVED: To provide a multi-phase converter with dynamic phase adjustment, which has highly efficient response characteristics.
SOLUTION: The multi-phase converter includes a VR control unit 102, a driver filter circuit 104 and a feedback circuit 106, and an adjusted voltage supply source VR is given to a load 110. The VR control unit includes a logic and a circuit to supply a drive signal P1:PN having its pulse width modulated to the phase leg in the driver filter circuit 104. The feedback circuit is coupled to a VR node and the driver filter circuit 104 to supply a voltage or a current feedback signal to the VR control unit 102. Thereby the output voltage VR is adjusted, and a phase leg having its phases deviated differently is dynamically controlled to maintain a desired operation efficiency.
