Signal is used to make Enable Pin keep effective, and self-sustaining disablement signal is used to make Enable Pin fail.
Wherein, self-sustaining signal is used to make Enable Pin keep effective, it can be understood as：By driving mould
The self-sustaining signal inputted in 2 pair of second input 21 of block signal resulting after changing,
Exported from the second output end 22 to Enable Pin, Enable Pin can be made effective.Similarly, self-sustaining
Disablement signal is used to make Enable Pin fail, it can be understood as：Pass through 2 pair of second input of drive module
The self-sustaining disablement signal inputted in 21 signal resulting after being changed, from the second output end
After 22 output to Enable Pins, Enable Pin can be made to fail.
Self-sustaining signal and self-sustaining disablement signal in the optional implementation are above-mentioned optional
Implementation in signal to be driven specific implementation.
If it should be noted that processor monitors the 3rd control signal, illustrating the first modular converter
1 can receive wake-up signal, therefore can be defeated by the first output end 11 of the first modular converter 1
The signal gone out so that Enable Pin is effective；If processor monitoring makes in principle less than the 3rd control signal
Energy end can fail；But, in technical scheme provided in an embodiment of the present invention, processor can be passed through
Self-sustaining signal is sent to drive module 2 in the Enable Pin valid period (during having wake-up signal),
So that Enable Pin remains valid.In this manner it is achieved that after no wake-up signal so that electricity
Control part keeps the power-up state of a period of time, and within the period, processor can be important to some
