摘要： A current control circuit controls a current from a current drawing circuit to which a primary coil of a transformer is connected. A first N channel transistor has a source connected to the current drawing terminal and has a body diode that directs a current from the source to a drain. A second N channel transistor has a drain connected to the drain of the first N channel transistor and a source connected to a ground. The second N channel transistor has a body diode that directs a current from the source to the drain. The first and second N channel transistors are turned on to direct a current from the current drawing terminal to the ground via the first and second N channel transistors. The first and second N channel transistors are turned off to stop the current from the current drawing terminal. Further, the body diode of the first N channel transistor inhibits current flowing from the ground to the primary coil of the transformer.
