Claim 0:
1. A power control unit configured to control an efficiency of a charge pump converter having a first input terminal and a second input terminal, a primary attenuator and a secondary attenuator between said first input terminal and said second input terminal, a first output terminal, a second output terminal, a secondary attenuator controlling terminal and a primary attenuator controlling terminal configured to be plugged to said power control unit, said primary attenuator controlling terminal and said secondary attenuator controlling terminal being configured to attenuate or amplify a signal of said first input terminal and said second input terminal, said power control unit comprising:
a first control circuit configured to sense an output power of said charge pump converter through said first output terminal and said second output terminal and transmit a sensed power value as a function of the sensed output power; and
a second control circuit configured to receive said sensed power value, establish a control value, and send said control value to said secondary attenuator controlling terminal and said primary attenuator controlling terminal so as to attenuate or amplify a signal of at least one input signal,
wherein the first control circuit is further configured to control an output current from the charge pump converter and measure an output voltage between the first output terminal and the second output terminal at lower input power levels across the first input terminal and the second input terminal, and/or control the output voltage and measure the output current at higher input power levels, and
wherein the first control circuit further comprises a first power input terminal configured to sense the output current and/or the output voltage value of the charge pump converter, and a second power input terminal, a resistive divider connected between the first power input terminal and the second input terminal to be compared in a comparison circuit to an internal reference configured to set a reference value, and a current limited buffer at an output of the first control circuit linked to the second control circuit.
