    摘要: A shutter circuit is provided for a multi-channel converter to blank the switching noise produced by the switching of the converter. The shutter circuit monitors the switching of the switches in the output stages of the converter, and when one channel performs switching, the shutter circuit will send a signal to other channels to block the current sensors thereof. The current sensors are so blocked for a period not to sense the switching noise. The mutual interference between the channels due to the switching noise of the converter is eliminated.

    摘要: A switching regulator may operate in a synchronous mode or an asynchronous mode. When the load current is higher than a threshold, the switching regulator switches a pair of serially connected high side and low side switches with a pulse width modulation signal. When the load current is lower than the threshold, the pulse width modulation signal is blocked not to switch the low side switch, the switching regulator switches only the high side switch with the pulse width modulation signal, the low side switch remains off, and a diode serially connected to the high side switch acts as a rectifier.
