Working Principles

The MAX755ESA+T is a step-up DC-DC converter that converts a low input voltage to a higher output voltage. It utilizes a switching regulator topology to achieve high efficiency. The input voltage is applied to the Vin pin, and the SW pin controls the switching of the internal power MOSFET. The feedback (FB) pin monitors the output voltage and adjusts the duty cycle of the switching waveform to maintain a stable output voltage. The EN pin enables or disables the converter.
