The **MPV380Z8QJ-R** is a specific part number belonging to the **MPV** series of High-Efficiency Power Modules manufactured by Monolithic Power Systems (MPS). These are typically high-density, multi-rail power management solutions designed for space-constrained applications. --- ### 1. Key Technical Specifications Based on the MPS nomenclature for this series, here are the primary electronic characteristics: | Parameter | Description | | :--- | :--- | | **Component Type** | DC-DC Step-Down (Buck) Power Module | | **Input Voltage Range** | Typically 4V to 16V (standard for the series) | | **Output Current** | High-current capability (often 10A - 30A depending on configuration) | | **Package Type** | QFN (Quad Flat No-Lead) or BGA with integrated inductor | | **Control Logic** | Pulse Width Modulation (PWM) with high-speed transient response | | **Efficiency** | Up to 95% at peak loads | --- ### 2. Core Electronic Components (Internal) The "MPV" series is known as a **Power Module**, meaning it integrates several discrete components into a single IC package: 1. **Switching Controller:** The "brain" that regulates the duty cycle to maintain a steady output voltage. 2. **Power MOSFETs:** High-side and Low-side transistors integrated into the silicon to reduce parasitic inductance. 3. **Power Inductor:** Unlike standard DC-DC converters, this module contains the **inductor inside the package**, saving significant PCB real estate. 4. **Feedback Network:** Precision resistors and compensation circuits for stability. --- ### 3. Application Areas These parts are designed for high-performance computing environments where board space is at a premium: * **FPGA & DSP Powering:** Providing clean, high-current rails for Xilinx or Intel FPGAs. * **Networking Equipment:** Used in routers and switches for core power. * **Storage Systems:** High-density SSD controllers and RAID arrays. * **Industrial Automation:** Point-of-Load (PoL) regulation for embedded systems. --- ### 4. Part Number Breakdown (Prefix/Suffix) * **MPV:** Monolithic Power Vertical/Module series. * **380:** Specific architecture identifier (often relating to internal voltage/current rating). * **Z:** Usually denotes a lead-free (RoHS) Green package. * **QJ:** Specific package sub-type (QFN/BGA variant). * **-R:** Indicates "Tape and Reel" packaging for automated SMT assembly.
