Working Principles

The TPS2055D operates by receiving an input voltage through the IN pin. The EN pin controls the power distribution to the outputs, allowing selective powering of individual components. The IC incorporates overcurrent protection, which monitors the output currents and shuts down the corresponding output in case of excessive current flow. This protects the components from damage due to overloading or short circuits.
