N2 - This paper introduces a new voltage regulator module (VRM) that hybrids a highly efficient switched-inductor converter as the main unit with a loadside switched-capacitor based converter to assist during load transient events. The resulting hybrid-VRM exhibits improved dynamic performance for both loading and unloading transient events, while maintaining a compact design with reduced stress of the components. The hybrid controller that has been developed allows operation based on output voltage measurement alone, further reducing the circuit complexity. The operation of the VRM is verified on a 30W, 12V-to-1.5V prototype, demonstrating a near-ideal transient recovery.
