| Abstract: | 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 t... |
