    Abstract: The disclosure provides a centrifugal fan including a housing and a blade module. The housing includes a lower cover, a side wall, and an upper cover. Two ends of the side wall are respectively connected to the lower cover and the upper cover to define an internal space. The lower cover includes a plurality of lower air inlets. The blade module is arranged in the internal space, and includes a hub and a plurality of blades. The hub is rotatably arranged on the lower cover. The blades are arranged around the hub. The lower air inlets are located on the periphery of the hub, and each lower air inlet includes an outer edge relative to a rotational axis of the hub. At least one of two ends of at least one of the lower air inlets includes a protruding portion at a position corresponding to the outer edge.

    Abstract: A power supply phase doubling system includes a pulse width modulation (PWM) controller and first and second phase doubling chips. The PWM controller outputs a PWM signal. The first phase doubling chip is operated at a power supply voltage and has a first PWM output pin to generate a first control signal and a second control signal according to the PWM signal, and generates a first output signal according to the first control signal. The second phase doubling chip is operated at the power supply voltage, has a second PWM output pin, and is configured to generate a second output signal according to the second control signal. The first and second phase doubling chips are respectively switched between a master mode and a slave mode according to a voltage level of the first PWM output pin and a voltage level of the second PWM output pin.

    Abstract: A fixing assembly is suitable for being arranged on a circuit board and configured to fix an expansion card. The fixing assembly includes a body and a buckle structure. The buckle structure includes a pressing part, a buckle part, an elastic member, and a base. The pressing part is away from the circuit board. An end of the buckle part is connected to the pressing part and has an inclined surface and a blocking surface connected to each other. The blocking surface has a gap with the top surface. The elastic member is connected to another end of the buckle part. When a first end of the expansion card is connected to the connector, a second end of the expansion card slides along the inclined surface to the top surface and is fixed in the gap by being abutted by the blocking surface.

    Abstract: A power management method for an electronic device is provided. The electronic device includes a processing unit with a core and configured to execute an application program and a functional element. The power management method includes the following steps: determining a maximum frame count per second of a scene; down-tuning a frequency setting value of the core; detecting an actual frame count per second of the scene; determining a change in power consumption of the processing unit and a temperature of the functional element when the actual frame count per second is equal to the maximum frame count per second; and down-tuning the frequency setting value when the power consumption does not increase and the temperature is lower than a preset temperature value, and restoring the frequency setting value when the power consumption increases or the temperature is higher than or equal to the preset temperature value.

    Abstract: A circuit board is adapted for inserting an expansion card with an electrical contact part, a non-electrical convex part, and a positioning part. The circuit board includes a board body, a slot, a release structure, and a transmission mechanism. The slot is disposed on the board body and includes a socket, a connecting end, and an outer surface. The socket is adapted for the electrical contact part to be inserted. The release structure is movably disposed at the connecting end and includes a limiting part. The transmission mechanism is disposed in the socket, adjacent to the connecting end, or adjacent to the outer surface. The transmission mechanism includes a driving member and a linking member. The driving member is adapted for contacting the electrical contact part, the non-electrical convex part, or the positioning part. The linking member is disposed between the driving member and the release structure.
