Working Principles

The MAX5955BEEE+TG002 is a power management IC designed to efficiently convert an input voltage into multiple regulated output voltages. It utilizes synchronous rectification and programmable current limit techniques to achieve high efficiency and precise control over the output currents.

The device operates by regulating the duty cycle of internal switches, which control the flow of current through the inductor. This enables the conversion of the input voltage to the desired output voltage levels. The programmable current limit feature allows users to set the maximum current that can be drawn from each output channel, providing protection against overloading.

Thermal shutdown protection ensures that the device automatically shuts down if the temperature exceeds a certain threshold, preventing damage due to overheating.
