  • Abstract
    In this study, implementing a dynamic quick response with high-frequency feedback control (HFFC) of the deformable constant on-time (COT) control for Buck converter on-chip is proposed. The concept uses the HFFC to filter Vout at the load transient to change the on-time width dynamically, preventing Vout from dropping markedly. Finally, 12 V input voltage, 3.3 V output voltage and 60 W output power with the HFFC are implemented to achieve a dynamic quick response for the integrated circuit of the proposed constant frequency COT for Buck converter. Experimental and SIMPLIS simulation results are compared to verify the viability and superiority of the proposed approach.
