The part number **47LPQ-62W-R/Q** corresponds to a specialized **Quarter-Brick DC-DC Converter** typically manufactured by companies like Murata or specialized power module providers. These components are designed for high-efficiency power conversion in telecommunications and computing environments. --- ### 1. General Specifications The "47LPQ" series belongs to the family of isolated, board-mounted power modules. Below are the typical technical characteristics for this specific model: | Parameter | Typical Value / Range | | :--- | :--- | | **Form Factor** | Quarter-Brick (approx. 2.30" x 1.45") | | **Input Voltage** | 36V to 75V DC (Standard Telecom Input) | | **Output Voltage** | 12V DC (Standard "62W" variant configuration) | | **Max Power Output** | ~60W to 62W | | **Isolation** | 1500V DC to 2250V DC | | **Efficiency** | Up to 90% - 94% | --- ### 2. Breakdown of the Part Number While nomenclature varies slightly by manufacturer, the suffix codes generally represent the following: * **47LPQ**: The series designation for Low Profile Quarter-brick converters. * **62W**: Indicates the power rating or specific voltage/current combination (62 Watts). * **-R**: Usually signifies **RoHS Compliance** (Restriction of Hazardous Substances). * **-Q**: Often indicates a specific **Pin Length** (shorter pins for SMT/wave soldering) or a specific **Thermal/Baseplate** option for heat sinking. --- ### 3. Key Electronic Features * **Remote On/Off Control:** Allows the system to enable or disable the power module via a logic signal. * **Output Trim:** Allows the user to adjust the output voltage slightly (usually ±10%) using an external resistor. * **Protection Circuits:** * **OTP:** Over Temperature Protection. * **OCP:** Over Current Protection (Hiccup mode). * **UVLO:** Under Voltage Lockout (prevents operation if input voltage is too low). * **Fixed Frequency Switching:** Reduces electromagnetic interference (EMI) and makes filtering more predictable. --- ### 4. Common Applications Due to its high power density and isolation, this part is commonly used in: 1. **Distributed Power Architectures (DPA):** Converting high-voltage bus power down to intermediate voltages. 2. **Telecommunications:** Powering base stations and switching equipment. 3. **Industrial Controls:** Providing stable DC power in environments with fluctuating input voltages. ---
