INTEGRATED CIRCUIT COMPRISING VOLTAGE MODULATION CIRCUITRY AND METHOD THEREFOR |
摘要 |
An integrated circuit comprising voltage modulation circuitry arranged to convert an input voltage level at an input node to an output voltage level at an output node. The voltage modulation circuitry comprises a switching element arranged to connect the input node to the output node when in an ON condition, and switching control module operably coupled to the switching element and arranged to control the connection of the input node to the output node by the switching element in accordance with a switching frequency. The voltage modulation circuitry further comprises frequency control module operably coupled to the switching control module and arranged to receive an indication of the input voltage level at the input node, and to configure the switching frequency based at least partly on the input voltage level indication. |
