The power stage circuit has a pair of switches, an output inductor, and an output capacitor. The control circuit has a current-sensing unit (CCS), an error-amplifying (EA) and transient-holding (TH) unit, a transient-optimized feedback unit (TOF), and a PWM generation unit. The CCS senses an output capacitor current. The EA with the TH receives a feedback voltage and a reference voltage to generate an error signal. The TOF receives the feedback voltage and the reference voltage to generate a proportional voltage signal by a variable gain value. The PWM generation unit receives the proportional voltage signal and a sensing voltage signal to generate a PWM signal. When the proportional voltage signal equals the sensing voltage signal, the switches are controlled by the PWM signal at an optimal time point so that transient responses are optimized."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Buck converter with a variable-gain feedback circuit for transient responses optimization","description":"A buck converter includes a power stage circuit and a control circuit.
