  • Publication number: 20190260291
    Abstract: A power supply covering power sharing and overshoot preventing functions. In the power supply, a first eFuse is used to deliver a first input power source to a first load at a first bus terminal, and a second eFuse is used to deliver a second input power source to a second load at a second bus terminal. When the current flowing through one eFuse hits its current limit threshold, the other input power source kicks in to provide power support. The current limit threshold of each eFuse is set to be lower than its maximum rated current.

  • Publication number: 20190260224
    Abstract: A power supply covering both power sharing and power backup functions run in a more efficient and flexible way. The power supply adopts a power sharing converter coupled between a first bus terminal and a second bus terminal, so that if one of the bus terminals provides insufficient power, the other bus terminal kicks in by way of the power sharing converter to provide power support. In addition, a storage capacitor may also kick in to provide power support if one of the bus terminals provide insufficient power via or not via the power sharing converter.
