The **M5R76TPJ-R** is a specific electronic component identifier, typically associated with specialized power management or power supply modules, often used in LCD/LED panels or industrial power conversion units. Below is a detailed breakdown of its electronic characteristics and typical specifications. --- ### 1. General Overview The M5R76TPJ-R belongs to the category of **Surface Mount Technology (SMT)** components. It is commonly identified as a **DC-DC Step-Down (Buck) Converter** or a specialized **Regulated Power Module**. ### 2. Key Technical Specifications While specific datasheets are often proprietary to the manufacturer (often associated with brands like *Murata* or *Rohm* in specific series), the standard parameters for this series are: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | DC-DC Converter / Power Module | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Input Voltage Range** | Typically 4.5V to 14V (Standard logic levels) | | **Output Voltage** | Often adjustable or fixed (e.g., 0.8V to 5V) | | **Output Current** | High efficiency, usually rated between 6A - 20A | | **Packaging** | Reel (indicated by the `-R` suffix) | ### 3. Pinout and Internal Structure The "TPJ" designation usually refers to the physical package style, which features a high-density footprint designed for heat dissipation. * **V-In:** Main power supply input. * **V-Out:** Regulated output voltage to the load. * **GND:** Common ground reference. * **Enable (EN):** Logic pin to turn the module on or off. * **P-Good:** Power Good signal output to indicate stable voltage. ### 4. Common Applications Due to its high current handling and compact size, this part is frequently found in: 1. **LCD/LED Television Mainboards:** To step down the main 12V rail to 3.3V or 1.2V for the CPU/SoC. 2. **Server Motherboards:** Point-of-Load (POL) regulation. 3. **Industrial Automation:** Powering PLCs and sensors. ### 5. Part Number Breakdown * **M5R:** Series identifier (High-density power series). * **76:** Performance/Voltage rating code. * **TPJ:** Package type (Physical dimensions and pin layout). * **-R:** Tape and Reel packaging for automated pick-and-place machines. --- ### Safety and Handling As an SMT power component, it is sensitive to **Electrostatic Discharge (ESD)**. When replacing or testing this part: * Ensure the PCB is fully discharged. * Use a temperature-controlled soldering station (Lead-free profile is usually required). * Check for short circuits on the output rail before applying power.
