摘要：
On the basis of PWM-based peak current sampling DC-DC converter, the circuit uses superimposition of sampling signal and slope compensation signal, and consists of peak current sampling amplifier, slope compensation circuit, and superimposition circuit. The peak current sampling amplifier converts current sampling signal into current and then inputs it onto superimposition circuit. The slope compensation utilizes a fixed slope. By designing properly slope compensation current, based ondifferent duty-cycle, the different compensation current signal is superimposed onto current sampling signal to realize slope compensation. The superimposed voltage signal is sent to PWM comparator to control the driving signal and control the power transistor switch.
