摘要： A system includes an input voltage node configured to provide an input voltage. The system also includes a load and a switching converter coupled between the input voltage node and the load. The switching converter is configured to provide an output voltage to the load based on the input voltage. The switching converter includes gate driver circuitry and a comparator coupled to the gate driver circuitry. The switching converter also includes a constant ripple injection circuit coupled to the comparator. The constant ripple injection circuit is configured to provide a positive current sense signal and a negative current sense signal to the comparator based on the input voltage and the output voltage.

摘要： A converter system includes a first switch, a sample-and-hold unit configured to provide a comparison signal based on a feedback signal when the first switch is switched off, and hold the comparison signal independent from the feedback signal when the first switch is switched on, and a pulse-width-modulation (PWM) generator, coupled between the sample-and-hold unit and first switch, configured to generate a PWM signal based on the comparison signal, wherein the first switch is configured to be switched on and off based on the PWM signal.
