Abstract
The present disclosure relates to power converter circuitry, and in particular to power converter circuitry for providing a supply voltage to a load such as amplifier circuitry. In one aspect the invention provides a system comprising: amplifier circuitry; and power converter circuitry for receiving a supply voltage and providing an output voltage to the amplifier circuitry, the power converter circuitry comprising: a control loop for regulating an output voltage of the power converter circuitry in accordance with a target output voltage value; and controller circuitry configured to adjust the target output voltage value if the supply voltage to the power converter circuitry is within a first predefined threshold of a requested output voltage of the power converter circuitry.
