Summary:Techniques to control the start point of an output voltage of a power supply for a short period after receive a "stop switching" signal, which will switch a DC-DC switching regulator from a pulse width modulation (PWM) mode to a linear mode to precisely position the output voltage at a certain level. In this way, the power supply can remove any output ripple caused by the PWM mode and can minimize or remove the sampling error to a low-power system in every cycle. In addition, the power supply can intelligently communicate a "power ready" signal back to the system, resulting in a synchronized system.
