| 发明名称 | System and method for switched power supply current sampling | ||
| 摘要 | According to an embodiment, a method of operating a switching power supply includes applying a periodic switching signal to a first switch that is coupled to an output node, detecting an offset delay between applying the periodic switching signal and a change in voltage of the output node, calculating a corrected midpoint of a half phase of the periodic switching signal based on the offset delay, generating a sampling pulse based on the corrected midpoint, and sampling a current at the output node according to the sampling pulse. | ||
