  • Fast transient power supply with a separated high frequency and low frequency path signals
    Patent number: 9831781
    Abstract: A power interface device includes a main switching converter, an auxiliary switching converter, and a feedback sense circuit. The main switching converter is coupled to an input terminal and an output terminal and configured to operate at a first switching frequency to source a low frequency current from the input terminal to the output terminal. The auxiliary switching converter is coupled to the input terminal and the output terminal in parallel with the main switching converter and configured to operate at a second and higher switching frequency than the first switching frequency to source a fast transient high frequency current from the input terminal to the output terminal.
    Type: Grant
