Abstract

PURPOSE:To make an accurate protection operation, by making the level oscillation frequency large by detecting it in case the screen voltage exceeds the constant value, controlling the detection circuit by the rise of the power supply voltage, and lessening the rising degree of the oscillation frequency of the level oscillation circuit.
