Working Principles

The MAX759CPD is a step-up DC-DC converter that utilizes a high-frequency switching regulator to efficiently convert a lower input voltage to a higher output voltage. It employs an internal power switch and synchronous rectification to minimize power losses during the conversion process. The feedback pin (FB) is used to regulate the output voltage, while the enable pin (EN) controls the device's operation. The soft-start pin (SS/TR) allows for controlled startup and shutdown, preventing excessive inrush current.
