Working Principle

The working principle of the PT79SR115T is based on a buck converter design. This type of converter is used for transforming a higher input voltage to a lower output voltage. It works by switching the input voltage at a high frequency and then regulating the output voltage. The DC-DC converter has an internal switch which is used to control the amount of current that flows through the inductor. The conversion process takes place with the help of the synchronous rectification, which improves the efficiency of the circuit.

The PT79SR115T also features an internal voltage regulator. This helps to ensure that the output voltage remains constant, even if the input voltage fluctuates. The converter also features the soft-start feature which ensures that the output voltage ramps up slowly before reaching its full power level. This helps to reduce the current surge which occurs during the startup of the DC-DC converter.

The PT79SR115T is also equipped with over current and short circuit protection. This prevents the module from being damaged due to excessive current or short circuit conditions. The module also has built-in thermal shutdown, which helps protect the device from overheating.
