  • Publication number: 20240146205
    Abstract: A flyback power converter includes a power transformer, a first lossless voltage conversion circuit, a first low-dropout linear regulator and a secondary side power supply circuit. The first low-dropout linear regulator (LDO) generates a first operation voltage as power supply for being supplied to a sub-operation circuit. The secondary side power supply circuit includes a second lossless voltage conversion circuit and a second LDO. The second LDO generates a second operation voltage. The first operation voltage and the second operation voltage are shunted to a common node. When a first lossless conversion voltage is greater than a first threshold voltage, the second LDO is enabled to generate the second operation voltage to replace the first operation voltage as power supply supplied to the sub-operation circuit; wherein the second lossless conversion voltage is lower than the first lossless switching voltage.

  • Patent number: 11925002
    Abstract: A casing structure with functionality of effective thermal management is disclosed, which consists of a casing member, a low thermal conductivity medium, a second heat spreader, and a first heat spreader. When a user operates the electronic device, heat generated from CPU and/or GPU is transferred to the second heat spreader via the first heat spreader, and then is two-dimensionally spread in the second heat spreader. Consequently, the heat is dissipated away from the casing member to air due to the outstanding thermal radiation ability of the casing member. The low thermal conductivity medium is adopted for controlling a heat transfer of heat transferring paths from the heat source and ends to the casing member. By applying the casing structure in an electronic device by a form of a top casing and/or a back casing, an outer surface temperature of the casing member can be well controlled.

    Abstract: The present invention provides a circuitry within a router or a switch, wherein the circuitry comprises a priority decision circuitry and a per-stream filtering and policing circuitry. The priority decision circuitry is configured to determine a priority of a frame received from a port of the router or the switch. The per-stream filtering and policing circuitry is configured to classify the frame into a first-type frame, a second-type frame or a third-type frame, wherein if the frame is determined as the first-type frame, the per-stream filtering and policing circuitry forwards the frame; if the frame is determined as the third-type frame, the per-stream filtering and policing circuitry discards the frame; and if the frame is determined as the second-type frame, the per-stream filtering and policing circuitry changes the priority of the frame, and the per-stream filtering and policing circuitry forwards the frame with the changed priority.
