Working Principles

The L5956PDTR is a power management IC that utilizes a buck converter topology to efficiently regulate the output voltage. It incorporates high-side and low-side MOSFETs, which are controlled by an internal PWM signal generated by the integrated controller. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the PWM signal to maintain the desired output voltage. The soft-start function gradually ramps up the output voltage during startup to prevent excessive inrush current.
