    摘要: A single wire serial interface for power ICs and other devices is provided. To use the interface, a device is configured to include an EN/SET input pin. A counter within the device counts clock pulses sent to the EN/SET input pin. The output of the counter is passed to a ROM or other decoder circuit. The ROM selects an operational state for the device that corresponds to the value of the counter. In this way, control states may be selected for the device by sending corresponding clock pulses to the EN/SET pin. Holding the EN/SET pin high causes the device to maintain its operational state. Holding the EN/SET pin low for a predetermined timeout period resets the counter and causes the device to adopt a predetermined configuration (such as off) until new clock pulses are received at the EN/SET pin.

    摘要: A method for pulse modulation control of switching regulators includes positioning a series of parallel FET-type switches (high-side switches) between the input side of an inductor and the voltage supply. A second parallel series of FET-type switches (low-side switches) are used to connect the input side of the inductor to ground. A control module enables one or more of the high-side switches at the start of each switching cycle. The enabled high side switches remain enabled until the output of the buck-type switching regulator is within regulation or a current limit through the high-side switches has been exceeded. The control module then disables all high-side switches and enables an equivalent number of low-side switches. The low-side switches remain enabled until the output has fallen below regulation or current has ceased to flow from the inductor to the load of the regulator.
