Working principle

The basic working principle of the MB39C031WQN-G-441-JNEFE1 is managing and delivering current between input and output terminals. The device contains 3 stages. The input stage acts as an AC to DC converter, the intermediate stage is for managing the current and the output stage delivers the Regulated DC output to the load.

The input stage consists of the PWM controller, the current sensing amplifier, the synchronous rectifier switch, the integrated high-side switch and the lower side switch MOSFET. It performs the task of voltage regulation and provides high-frequency switching. It is responsible for switching the power electronics path between high-side and low-side. The current sensing stage measures the input current and includes the current sensing amplifier, the current limit comparator and the voltage feedback loop components. These components are used to adjust the duty cycle of the PWM controller to maintain the current limit.

The intermediate stage is designed to increase the frequency of the PWM signal. It has two main components, one is the Error Amplifier and the other is the voltage generator. The Error Amplifier is used to compare the output voltage & the reference voltage (provided by the voltage generator) and generate an error signal to control the duty cycle of the PWM controller. This device also has an output voltage adjusting circuit connected to the output stage to maintain the stable output voltage.

The output stage consists of one or two MOSFETs that are responsible for delivering the Regulated DC output to the load. In the MB39C031WQN-G-441-JNEFE1, the output stage is designed to protect the device from over current, over voltage, and output over temperature situations.
