Power supply apparatus
First Claim
1. A power supply apparatus for supplying an output voltage to a load, comprising:
- a power output unit, electrically connected to the load and used to adjust and supply the output voltage to the load according to at least one driving signal;
a feedback unit, electrically connected to the power output unit and used to detect the output state of the power output unit and output a corresponding detection result; and
a control unit, electrically connected to the feedback unit and the power output unit and used to skip a part of the pulse for an internal clock and select to output the skipped internal clock signal as the driving signal, wherein the control unit determines the skipping ratio for the internal clock according to the detection result output by the feedback unit, and the skipping ration is dynamically adjusted as the load is changed.

Abstract
A power supply apparatus for supplying an output voltage to a load is provided, which comprises a power output unit, a feedback unit and a control unit. The power output unit adjusts and supplies the output voltage to the load in accordance with at least one driving signal. The feedback unit dynamically detects output condition of the power output unit and outputs the corresponding detection result. The control unit determines a skipping ratio for an internal clock in accordance with the detection result output from the feedback unit, and outputs the internal clock with a part of the pulses being skipped to act as the driving signal.
