The part number **47LPQ-A0B-R** belongs to the **47L series** of high-performance, ultra-low profile DC-DC converters, typically manufactured by companies like **Murata Power Solutions** (often part of their Okami product line). --- ## 1. Technical Specifications The "LPQ" suffix generally denotes a specific configuration regarding output voltage, packaging, and environmental compliance. | Feature | Specification | | :--- | :--- | | **Component Type** | Non-isolated Point-of-Load (PoL) DC-DC Converter | | **Input Voltage Range** | Typically 7V to 14V (Nominal 12V) | | **Output Voltage** | Often adjustable or fixed (commonly 0.6V to 5.0V range) | | **Max Output Current** | High density (likely 20A - 40A depending on specific sub-series) | | **Form Factor** | Ultra-low profile LGA (Land Grid Array) | | **Efficiency** | Up to 95% - 96% | --- ## 2. Key Features * **Ultra-Low Profile:** Designed for space-constrained applications like blade servers and high-density networking gear. * **High Power Density:** Provides high amperage in a very small footprint. * **Thermal Management:** The LGA packaging allows for efficient heat dissipation directly into the PCB copper layers. * **Protection Suites:** Usually includes: * Over-Current Protection (OCP) * Over-Temperature Protection (OTP) * Under-Voltage Lockout (UVLO) --- ## 3. Part Number Breakdown (Typical) While internal manufacturer codes vary, the suffix **-R** almost universally indicates the packaging method: | Suffix | Meaning | | :--- | :--- | | **47L** | Series Identifier (High-efficiency PoL) | | **PQ** | Power/Package configuration code | | **A0B** | Specific revision or voltage set-point code | | **-R** | **Tape and Reel** (indicates it is packaged for automated SMT assembly) | --- ## 4. Common Applications These components are critical in modern electronics where board space is at a premium but power demands are high: 1. **FPGA/DSP Power:** Providing precise, low-voltage high-current rails. 2. **Telecommunications:** Network routers and high-speed switches. 3. **Computing:** Server motherboards and data storage arrays.
