  • Power converter with asymmetric switch levels
    Patent number: 11996764
    Abstract: Described embodiments include a circuit for limiting power converter output ripple. A first transistor has a first current terminal receiving an input voltage, and a second current terminal coupled to a first capacitor. A second transistor has a third current terminal coupled to the first capacitor, and a fourth current terminal is coupled to a second capacitor. A third transistor has a fifth current terminal coupled to the second capacitor, and a sixth terminal coupled to a filter input. A fourth transistor has a seventh current terminal coupled to the second current terminal, and an eighth current terminal coupled to the sixth current terminal. A fifth transistor has a ninth current terminal coupled to the fourth current terminal, and a tenth current terminal coupled to the sixth current terminal.
