More Information
Summary:This invention provides a high efficient voltage-dropping converter with power-saving structure, in which, a first circuit generates an oscillation signal and a power-saving signal based on a feedback signal, a second circuit generates multiple switch signals based on said feedback signal and said oscillation signal to control multiple switch devices, and the off time of the switch signal prolongs along the reduction of the load, said power saving signal cuts off part of control circuit of said switch device and the voltage dropping converter at the cut-off time of the switch signal to save power under light load.
