1. DC-DC converter, comprise at least one power switch, be used to produce a pulse width modulation circuit to the gating pulse of described at least one power switch, be connected to an outputting inductance of described at least one power switch, a current detector that is used to detect by the electric current of described inductance in parallel with described inductance, it is characterized in that described current detector comprises a resistance and electric capacity that is cascaded, a peak point current control loop circuit, cooperate described pulse width modulation circuit to be used to respond described at least one power switch of described current detector control, described resistance and electric capacity have analog value, so that described current detector is a momentary current detecting device basically.
