Abstract: PURPOSE: A piezo-electric ceramic transformer and circuit for driving cold cathode fluorescent lamps using the same is provided to drive the transformer in a full wavelength mode by arranging the driving unit to have two input parts. CONSTITUTION: A piezo-electric ceramic transformer comprises a piezo-electric ceramic plate(210) operating at the full wavelength mode and which is constituted by a single central driving unit and two output units(213,214), wherein the driving unit has two inputs(211,212); four external electrodes(215,216,217,218) arranged at side surfaces of two inputs of the piezo-electric ceramic plate; two sets of internal electrodes(219a,219b,210a,210b) arranged in a multiple layer structure within the two inputs, wherein each layer is connected in parallel alternately to the left external electrodes(215,217) and right external electrodes(216,218); and two output electrodes(221,222) arranged at both ends of two outputs of the piezo-electric ceramic plate.
