| 摘要 |
<p>The invention relates to a voltage supply circuit comprising a first supply voltage input (IN1) that is connected to a first comparator (CMP1) and a first voltage regulator (REG1), the former (CMP1) controlling the latter (REG1). The circuit is also equipped with a second supply voltage input (IN2) that is connected to a second comparator (CMP2) and a second voltage regulator (REG2), the former (CMP2) controlling the latter (REG2). In addition, the circuit is provided with a supply voltage output (O) that is connected to the outputs of the two voltage regulators (REG1, REG2) and to the two comparators (CMP1, CMP2) in a feedback coupling.</p> |
