Working Principle
The working principle of the NCT3730S is based on switching the input voltage between two points, the high(VH) and the low(VL) in an alternating sequence. During the switching process, a synchronous pulse is generated, which is used to transfer power from the input voltage to the output voltage. This is done by using two transistors in combination with two diodes and a low pass filter.
The device also integrates protection features such as overvoltage, overcurrent and over-temperature. The integrated protection circuit ensures that the NCT3730S does not overload or experience too much heat, thus ensuring longer life and better performance.
