A VOLTAGE REGULATOR MODULE USING A LOAD-SIDE AUXILIARY GYRATOR CIRCUIT

The present invention introduces a new compact Voltage Regulator Module (VRM) solution that hybrids a buck converter with a resonant switched-capacitor auxiliary circuit that is connected at the load side. By using a new control concept of the present invention, the auxiliary circuit effectively mimics increased capacitance during loading and unloading transient events, reducing the burden on both the input and output filters, and reduces the current stress.
