从宽范围可变和低输入电压提供输出电压

Provision of an output voltage from a wide range variable and low input voltage
Abstract:
A circuit arrangement for providing an output voltage and/or an output current from an input voltage Vin, comprising: a first switching converter (10) having a storage element (120) and a first switching element (110), adapted to charge the storage element (120) from the input voltage Vin up to a threshold voltage and a second switching converter (20) having a second switching element (210) adapted to start with the threshold voltage at the storage element (120) and to provide the output voltage Vout and/or the output current Iout from the input voltage Vin, wherein the first switching element (110) has a minimum driving voltage, at and above which the first switching element (110) can perform switching operations, the second switching element (210) has a minimum driving voltage, at and above which the second switching element (210) can perform switching operations, and wherein the minimum driving voltage of the first switching element is smaller than the minimum driving voltage of the second switching element.
