Problems solved by technology

However, this will cause the pins of the MINI PCIE interface to heat up seriously due to excessive current, and reduce the transmission power; at the same time, the total voltage drop on the transmission path will also increase with the increase of the current, resulting in finally reaching the MINI PCIE interface. The voltage of the card terminal equipment is much lower than its normal working voltage, which causes the system to work abnormally

Abstract

The invention discloses a voltage control device. The device comprises a central control module, a voltage reduction controller and an interface module. The central control module is used for sendinga boosting request to a host device, so that the host device determines whether the host device has a boosting function or not, and when the host device has the boosting function, the output voltage is boosted to a target voltage and output; the interface module receives the target voltage; and when the host device has the boosting function and the target voltage is greater than a preset standardvoltage, the voltage reduction controller reduces the target voltage to be equal to the standard voltage to serve as a working voltage. The invention further discloses another voltage control device and another voltage control system, and the total power consumption of the interface device can be improved by improving the output voltage of the host device, so that the power consumption requirementof the interface device is met, the voltage drop and the energy loss of a power supply path are effectively reduced, and the stability and the compatibility of the system are ensured.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a voltage control device and system. Background technique [0002] The MINI PCIE (Mini PCI Express) interface is a general-purpose circuit interface consisting of a plug-in card and a connector. For a standard MINI PCIE card, affected by its own power supply specifications, the maximum peak power consumption it can obtain is relatively low. With the rapid development of communication networks, the specifications of wireless devices have developed explosively. For terminal devices using MINI PCIE cards, the demand for single-board power consumption is high, far exceeding the maximum peak power that standard MINI PCIE cards can provide. At this time, the power consumption of the standard MINI PCIE interface can no longer meet the demand. [0003] In the prior art, power consumption is improved by increasing the power supply current of the MINI PCIE interface. Howe...
