POWER SUPPLY CONTROL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18395075 titled 'POWER SUPPLY CONTROL DEVICE
The present disclosure introduces a power supply control device that generates an output voltage from an input voltage by switching driving an output stage based on a feedback voltage corresponding to the output voltage. An overcurrent protection signal is output when the current flowing through the output stage exceeds a predetermined overcurrent threshold. An overcurrent protection operation is then performed to limit the increase in current beyond the threshold, with the threshold set based on the elapsed time from the start of switching driving of the output stage.

Original Abstract Submitted
The present disclosure provides a power supply control device. An output voltage is generated from an input voltage by switching driving an output stage based on a feedback voltage corresponding to the output voltage. An overcurrent protection signal is output when a value of a current flowing through the output stage exceeds a predetermined overcurrent threshold. An overcurrent protection operation is performed in response to the overcurrent protection signal, and the overcurrent protection operation limits an increase in the current flowing through the output stage exceeding the overcurrent threshold. The overcurrent threshold is set according to an elapsed time from a start of switching driving of the output stage.
