Description
Technical Field
The invention relates to the field of board design, in particular to a self-adaptive load board energy-saving power supply circuit, a method, a device and a server.
Background
With the continuous development of multimedia cloud playing technology, the requirements of users on the audio and video playing quality are higher and higher. Especially in the server field, this requirement is more critical.
When the audio and video file is played, the audio and video hard decoding chip plays an important role. The audio and video hard decoding chip is independent of a main control CPU (Central Processing Unit), and the audio and video decoding work is independently finished through a special IC chip. Such as: the decompression of VCD/DVD audio and video and the compression of audio and video basically adopt independent audio and video hard decoding chips.
Usually, the decoding chip is integrated into the PCIE card, and the user may select the decoding chip and the PCIE card with different configurations according to the requirement. Since the configuration of the decoding chips is gradually improved, the power consumption and the number of the decoding chips are also increased, which makes the power supply of the PCIE board particularly critical.
Under normal conditions, the server designs a PCIE (Peripheral Component interface express) daughter card, and power supply from the motherboard to the PCIE card is realized by one gold finger. If the decoding chip power consumption required by the customer is small, the gold finger is wasted at the moment. If the number of decoding chips required by a client is large or the power consumption is large, the power of the board card is large at the moment, and the current flowing through the golden finger is large, so that the golden finger can generate heat seriously, the power supply efficiency is influenced, and the golden finger can be burnt out seriously to influence the reliability of a server system.
In summary, the existing power supply scheme has low power supply efficiency and poor reliability on one hand; on the other hand, the power supply strategy cannot be adjusted in real time according to the power consumption information of the board decoding chip, the flexibility is poor, and the power supply scheme cannot be optimal.
Fig. 1 shows a schematic diagram of a power supply scheme of a PCIE card of a decoding chip in the prior art, as shown in fig. 1, in some prior arts, no matter a load current is large or small, all loads are supplied with power by a designed gold finger, so as to ensure normal operation of a board card chip and the like.
In the prior art as shown in fig. 1, the scheme cannot adjust the change of the input end according to the change of the load, so that the load card can only be powered by a fixed golden finger no matter high power or low power. This results in:
on one hand, because the impedance of the golden finger is large, if the power on the board card is too large, the golden finger is heated, and the efficiency of the whole system link is low;
on the other hand, if the load power of the board card is smaller, the waste of the golden finger power supply PIN is caused, and the flexibility of the board card is greatly reduced.
