Working Principles

NCP6343DFCCT1G operates as a synchronous buck converter, converting the input voltage to a regulated output voltage. The integrated PWM controller generates a constant frequency signal to control the switching of the internal power MOSFETs. By adjusting the duty cycle of the PWM signal, the output voltage can be regulated. The soft-start function ensures a gradual ramp-up of the output voltage during startup, preventing excessive inrush current.
