A general embodiment includes a VX Detection Block coupled to the core block of a power converter. The VX Detection Block is coupled to VX and to a control circuit that disables operations of an associated converter circuit upon detection of large, rapid falls in VX during the dead time between clock phase signals, thereby prevent damaging current spikes. Some embodiments include a VIN Detection Block configured to detect and prevent excessive in-rush current due to rapidly falling values of VIN to the power converter. The VIN Detection Block is coupled to VIN, and to VX or VOUT in some embodiments, and to a control circuit to that disables operation of an associated converter circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"In-rush current protected power converter","description":"Circuits and methods for protecting the switches of charge pump-based power converters from damage if a VOUT short circuit event occurs and/or if VIN falls rapidly with respect to VX or VOUT.
