CONTINUOUS-CONTINUOUS CONVERTER BLOCK WITH MULTIPLE POWER SUPPLY VOLTAGES, CONTINUOUS-CONTINUOUS CONVERTER WITH MULTIPLE POWER SUPPLY VOLTAGES COMPRISING SAME AND ASSOCIATED ENVELOPE MONITORING SYSTEM

摘要

The present invention relates to a DC-DC converter block with multiple supply voltages comprising a power circuit, the power circuit comprising N depletion HEMT transistors (T3_1, T3_2, T3_N), where N is a higher natural number or equal to 3, the DC-DC converter block further comprising a gate driving circuit of the N depletion HEMT transistors (T3_1, T3_2, T3_N) of the power circuit, characterized in that the control circuit comprises HEMT transistors at depletion (T1_1, T2_1, T1_2, T2_2, T1_N, T2_N) configured to drive the gates of the N depletion HEMT transistors (T3_1, T3_2, T3_N) of the power circuit, and in that the power circuit is powered by N positive and non-zero supply voltages, namely a lower supply voltage (VDD_1), a higher supply voltage (VDD_N) and (N-2) intermediate supply voltages (VDD_2) parts between the lower (VDD_1) and upper (VDD_N) supply voltages.
