    • PURPOSE: A piezo transformer driving circuit is provided to improve driving efficiency of a piezo transformer by decreasing boost rate of voltage applied to an input terminal of the piezo transformer. CONSTITUTION: A piezo transformer driving circuit comprises: first and second switching devices (Q1,Q2), connected to an input power (Vin) in parallel as well as in serial, oprating on/off; an oscillating device (OSC) supplying opposite pulse signals to the first and the second switching device (Q1,Q2); and an inductor (L) connected between a common contact point of the first and the second switching means (Q1,Q2) and an input terminal of a piezo transformer (PT). The piezo transformer driving circuit is provided to improve efficiency by decreasing boost rate of the input voltage, and to make product miniaturized and product price decreased by changing currents of the inductor on both sides so as to reduce current capacity.
