The slow start of power supply in the circuit board of the communication system

The power module plays an important role in the communication system circuit board,the stability of the circuit board based on the performance of the power module.Proposes to use the MOSFET to control the slow start of the power module with anti-reverse and anti-overflow,it's able to reduce the strength of the current of the circuit broad when the power is to be on,protecting the device from momentary inrush current,making the circuit board works properly.To verify the reasonability and the feasibility of the design in detail,and measure the effects of the design compared to others.The stability of power current waveform and the actual effect shows that the method can meet the requirements of the power module in the communication system.
