1. one kind is converted to the DC-DC transducer of second dc voltage with first dc voltage, it is characterized in that:

  • Be connected to first switch of the input of described first dc voltage;

    Second switch, wherein said first and second switches are controlled by input signal, to generate described second dc voltage;

    Checkout equipment, the current level that is used for detecting described second switch is poor;

    AndControl circuit is controlled the delay of described input signal by monitoring described current level difference.
