摘要：A voltage/current controller device, particularly for interleaving switching regulators, comprises: a DC/DC converter having a plurality of modules, with each module including a drive transistor pair connected in series between first and second supply voltage references, a current sensor connected to one transistor in the pair, and a current read circuit connected to the sensor. Advantageously, the read circuit comprises a transconductance amplifier connected across the current sensor to sense a voltage signal related to a load current being applied to each module, the transconductance amplifier reading the voltage signal with the transistor in the conducting state.
