SWITCHING REGULATOR CONTROL CIRCUIT |
摘要 |
In the related art, there is a problem that the condition of a load is monitored in an indirect manner so that an efficiency enhancing effect is not obtained. A switching regulator control circuit includes an oscillator for generating a carrier signal and a transistor drive circuit for driving a switching transistor and a synchronous rectification transistor based on a PWM signal generated based on the carrier signal. The oscillator switches the frequency of the carrier signal based on the direction of a source-drain voltage of the synchronous rectification transistor. |
