Working Principles

The MAX758ACPA is a step-up DC-DC converter that utilizes an inductor to store energy and transfer it to the output. When the SW pin is switched on, current flows through the inductor, storing energy. When the SW pin is switched off, the stored energy is released, resulting in an increased output voltage. The feedback mechanism provided by the FB pin regulates the output voltage by adjusting the duty cycle of the switching operation.
