ADAPTIVE SWITCHING FREQUENCY ADJUSTMENT FOR A POWER SUPPLY |
| 摘要 |
Described herein are systems and methods for providing a variable switching frequency for a power supply. The system includes a controller and a filter. The controller generates a switching frequency for a power supply. The switching frequency is modified as a function of an input voltage and an output voltage. The filter provides the output voltage to a load based at least in part on the switching frequency generated by the controller. In one example, the controller adaptively modifies the switching frequency as a function of the input voltage and the output voltage in order to maintain a peak to peak current for an inductor. |
