A pulse modulator generates a pulse modulation signal such that an output of the buck DC/DC converter is pulse-modulated to approach a target state. An overcurrent detection circuit compares a low-side current flowing through a low-side transistor with a predetermined overcurrent threshold value to generate an overcurrent detection signal that is asserted when the low-side current is greater than the overcurrent threshold value. (i) In a first mode, the control pulse that is input to the driver circuit corresponds to the pulse modulation signal, and (ii) in a second mode, the control pulse takes a second level for a period during which the overcurrent detection signal is asserted and takes a first level during a fixed on time after the overcurrent detection signal is negated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Buck DC/DC converter, controller thereof and controlling method thereof, and electronic device","description":"The present disclosure relates to a buck DC/DC converter, a controller thereof and controlling method thereof, and an electronic device.
