The power protection unit 131 employs an Effect IC (electronic fuse/fuse), and when the current is too large, a built-in MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is turned off, so that the power protection unit has a high-speed current breaking function. Meanwhile, when an external power supply is connected, the efuse IC can absorb surge power in the power supply, so that a voltage clamp between two electrodes is positioned at a preset value, precision components in an electronic circuit are effectively protected from being damaged by various surge pulses, and the safe and reliable power supply input wide voltage conversion unit 132 is provided.
The segmented current and the clamping voltage can be set according to actual requirements. The breaking current can be set in a continuous interval of 1A to 5A, and the clamping voltage can be set to be LOW-3.8V, HIGH-5.7V or OPEN-13.3V.
The wide voltage conversion unit 132 adopts a boost IC, and can meet the requirement of outputting 5V by a DC-4.5V-5.5V input power supply. Compared with the design redundancy of DC-5V +/-5%, the design can meet the use scene of wider voltage and can normally work when the external input power supply has undervoltage.
Specifically, the power protection unit 131 employs a SY6875ADBC use IC. Of course, according to actual requirements, the power protection unit 131 may also use another efuse IC model, or adopt a design scheme of a recoverable fuse plus a TVS tube.

Specifically, the storage module 110 includes: a main control unit 111, and an SDRAM storage unit 112 and a FLASH storage unit 113 electrically connected to the main control unit 111, respectively.
Specifically, the main control unit 111 is further electrically connected to the power conversion module 120 and the SATA connector 140, and is configured to store data to be stored in the FLASH storage unit 113 and the SDRAM storage unit, respectively.
The data to be stored is data to be stored, which is sent to the main control unit 111 by the external device.
The main control unit 111 is electrically connected to the external device through the SATA connector 140, and when the external device needs to read the stored data, the external device can read the data through the SATA connector 140.
Specifically, the SDRAM storage unit 112 includes 1 to 2 SDRAM memories, and the FLASH storage unit 113 includes 1 to 8 FLASH memories.

Specifically, the power conversion module 120 supplies the converted voltage to the storage module 110.
The power conversion module 120 is a multi-power system, and receives power from an external device through the wide voltage conversion module 130.
In the present embodiment, the operating voltages of the main control unit 111 are 1.2V, 1.5V, 1.8V and 3.3V, respectively. Of course, the operating voltage of the memory module 110 may also be adaptively adjusted according to actual requirements.
Since the main control unit 111 has various working voltages, the voltage conversion function of the power conversion module 120 can meet the working voltage requirement of the main control unit 111, so as to ensure the normal execution of the functions of the main control unit 111. That is, the power conversion module 120 can convert the received power voltage into voltages 1.2V, 1.5V, 1.8V, and 3.3V required by the main control unit 111, respectively.
Specifically, the power conversion module 120 is a synchronous buck switching power supply chip.
In the circuit layout, it is necessary to consider that the analog and digital signals are separated, and the analog portion of the PCB of this embodiment is centrally disposed on a certain block of the circuit, so as to ensure that the analog signal does not generate a large interference to the high-speed data signal of the main control unit 111.

Considering the high-speed signal and multi-power system of the PCB, the PCB in the embodiment adopts 8 layers of boards, namely a top layer, a ground layer, a first signal layer, a first power layer, a second signal layer, a ground layer and a bottom layer; because multiple power supplies exist in the power supply layer, each power supply is uniformly distributed as much as possible in the design, the situation of narrow width is avoided, the power supply distribution of the power supply layer is matched with the layout of the top layer as much as possible, and the power supply distribution is ensured to be uniform; meanwhile, the power supply layer is slightly retracted relative to the stratum, and the 3H principle is met, so that the interference of signals is reduced; the wiring directions of the same signal layer are consistent, and the signal lines of different layers are arranged in an orthogonal mode, so that the interference among different signals can be effectively reduced.
The communication between the SDRAM memory unit 112 and the main control unit 111 is a super-high speed communication mode, so the two are as close as possible in layout, and meanwhile, the routing between the two strictly meets the 3W principle and the length of the equal signal line, and the serpentine line mode is adopted to ensure the equal length of the signal line clock line under the condition of insufficient space, so that the signal interference between parallel lines can be greatly reduced.
For key signals and small signals, the signals are isolated as much as possible, and power noise and the like are prevented from being connected in series with the signals; a proper decoupling capacitor is arranged at a power supply inlet, so that the stability of a chip power supply can be ensured; in addition to electrically connecting signals, the vias are also grounded when necessary to minimize power loops, particularly power filter loops.
Compared with the prior art, the solid state disk wide-voltage input system solves the problem of abnormal read-write function of the solid state disk caused by undervoltage of an external power supply when a plurality of solid state disks form a disk array for use through the wide-voltage conversion module.
An embodiment of the present invention further provides a solid state disk 200, as shown in fig. 4, where the solid state disk 200 includes the solid state disk wide-voltage input system 100. Since the solid state disk 200 adopts the solid state disk wide-voltage input system 100, the technical effect achieved is the same as that achieved by the solid state disk wide-voltage input system 100, and details are not repeated herein.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
