The part number **47DV-1011-R** typically refers to a specialized **DC-DC Converter** or a power module, often associated with manufacturers like *NetPower Technologies* or similar industrial power component suppliers. Below is a detailed breakdown of the electronic specifications and characteristics of this component. --- ### 1. General Specifications This part is designed for high-efficiency power conversion in telecommunications, networking, and industrial equipment. | Feature | Description | | :--- | :--- | | **Component Type** | Isolated DC-DC Converter | | **Input Voltage Range** | Typically 36V - 75V DC (Standard 48V Telecom Input) | | **Output Voltage** | 1.0V DC (High Current / Low Voltage) | | **Max Output Current** | ~11 Amps (Derived from the "1011" coding) | | **Form Factor** | 1/16th Brick or 1/32nd Brick (Ultra-compact) | | **RoHS Compliance** | Yes (Indicated by the "-R" suffix) | --- ### 2. Key Technical Features * **High Efficiency:** Uses synchronous rectification to achieve efficiency levels often exceeding 85-90%, reducing the need for heavy heatsinking. * **Isolation:** Provides galvanic isolation between the input and output circuits (typically 1500V DC or higher) to protect sensitive downstream logic. * **Protection Circuits:** * **OTP:** Over Temperature Protection. * **OCP:** Over Current (Short Circuit) Protection. * **UVLO:** Under-Voltage Lockout (prevents operation when input power is too low). * **Remote Sensing:** Includes pins to compensate for voltage drops across PCB traces, ensuring the load receives an exact 1.0V. --- ### 3. Pin Configuration (Typical) Most modules in this series follow a standard industrial footprint: | Pin Name | Function | | :--- | :--- | | **Vin(+) / Vin(-)** | Positive and Negative Input Voltage | | **ON/OFF** | Control pin to enable/disable the converter remotely | | **Vout(+) / Vout(-)** | Regulated 1.0V DC Output | | **Trim** | Allows the user to adjust the output voltage slightly (e.g., ±10%) | | **Sense(+) / Sense(-)** | Feedback lines for precise voltage regulation | --- ### 4. Applications This part is commonly used in environments requiring "Point-of-Load" (POL) regulation: 1. **Server Motherboards:** Powering high-speed CPUs or FPGAs that require a stable 1.0V core rail. 2. **Optical Networking:** Providing power to laser drivers and signal processors. 3. **Data Storage:** Powering SSD controllers and memory arrays.
