Title: Kohei Santo and Constant On-Time DC/DC Converter Control.
Introduction
Kohei Santo is an inventor based in Ikeda, Japan. His patent work includes a DC/DC converter design intended to reduce switching-frequency variations while using constant on-time control.
Latest Patents
Santo is credited with 1 patent: “DC/DC Converter Capable of Performing Constant On-Time Control with Reduced Variations of Switching Frequency.” The invention describes a driver circuit that operates switching elements using constant on-time control, alongside a monitoring circuit that identifies whether the converter is in a steady or abnormal state. An ON-timer circuit uses a duty-ratio-dependent reference voltage in steady operation and a fixed reference voltage in an abnormal state. Its control signal helps terminate the energy-storage interval in each switching cycle, supporting more consistent switching behavior.
Career Highlights
Santo is associated with Nisshinbo Micro Devices Inc. His listed patent reflects work on power-conversion circuitry and control methods designed to manage switching-frequency variation across operating conditions.
Collaborations
Shiro Matsushita and Kagehito Tanji are identified as Santo’s coworkers. The available information does not specify their roles in the patent or whether they collaborated on the invention.
Conclusion
Kohei Santo’s documented invention focuses on improving constant on-time control in a DC/DC converter by adapting its timing reference to the converter’s operating state.
