Abstract

The present invention is a high frequent power source apparatus, it can supply stable DC power source to load. Application to a precision voltage control circuit, which applicable to the pulse frequency modulation (PFM) circuit. The circuit can be the Cold Cathode Fluorescent Lamp (CCFL) tubes getting stable high frequent voltage and earn the optimal emitting efficiency. The circuit also has protected circuit to avoid the CCFL tubes injury in the, overload voltage and low voltage. The circuit can also be applicable to TFT LCD TV, or others large LCD panels, and develop the best display effect of the LCD tubes.
