| 发明名称 | Switching power supply having high-power integrated circuit and monolithic integrated circuit therefor | ||
| 摘要 | A switching power supply comprises one or more power supply stages that receive power from an input power source and that generate a regulated output voltage for powering a load. A controller monitors at least the regulated output voltage and generates at least one switch control signal for alternately opening and closing a switch so as to regulate the regulated output voltage. A monolithic integrated circuit is coupled to receive the switch control signal. The monolithic integrated circuit is separate from the controller and comprises a plurality of transistors capable of operation at voltage levels that are at least one order of magnitude higher than voltage levels within the controller integrated circuit. | ||

| 主权项 | 1. A switching power supply comprising: a controller configured to control one or more power supply stages that receive power from an input power source and that generate a regulated output voltage for powering a load wherein the controller is configured to monitor at least the regulated output voltage and to generate at least one switch control signal for alternately opening and closing a switch so as to regulate the regulated output voltage; and a monolithic integrated circuit separate from the controller and coupled to receive the switch control signal from the controller wherein the monolithic integrated circuit comprises a plurality of transistors capable of operation at voltage levels that are at least one order of magnitude higher than voltage levels within the controller. | ||
