Patent number: 10686365Abstract: A power supply controller having a shortened reset time due to a small hiccup voltage includes an electrical circuit providing a repeated voltage hiccup of a supply voltage of the controller of a switched-mode power supply (SMPS) when the controller enters a latched state. A plurality of comparators each have an input coupled with the controller supply voltage. A multiplexer and two latches are included, each coupled with one or more comparator outputs, and a restart controller is coupled with an output of one of the latches. The restart controller in various implementations toggles a switch to activate and deactivate a current sink to create the supply voltage hiccup. In other implementations, the switch is excluded and the restart controller toggles a voltage startup transistor to couple and decouple a voltage source with the supply voltage to create the voltage hiccup.Type: GrantFiled: April 2, 2019Date of Patent: June 16, 2020Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Zdenek Pfof, Jiri Bubla, Ivo Vecera
