The **RPL-08-R-T** is a high-performance, ultra-compact DC-DC converter module manufactured by **RECOM Power**. It belongs to the RPL series, which is known for its high power density and integrated inductor technology. ### 1. Key Technical Specifications The following table summarizes the primary electrical characteristics of the RPL-08-R-T: | Parameter | Specification | | :--- | :--- | | **Type** | Step-Down (Buck) Regulator | | **Input Voltage Range** | 2.75V to 17V | | **Output Voltage Range** | 0.6V to 5.5V (Adjustable) | | **Max Output Current** | 8 Amperes | | **Efficiency** | Up to 94% | | **Switching Frequency** | Adjustable (Typically 600kHz to 2MHz) | | **Package** | LGA (Land Grid Array) | | **Dimensions** | 7.0 x 7.0 x 4.4 mm | --- ### 2. Core Functional Features The RPL-08-R-T is designed to simplify the power stage of a PCB by integrating several discrete components into a single module. * **Integrated Inductor:** Unlike standard switching regulators that require an external power inductor, the RPL-08-R-T has the inductor built-in. This reduces EMI (Electromagnetic Interference) and saves significant board space. * **Adjustable Output:** The output voltage is set via an external resistor divider, providing flexibility for various logic rails (1.2V, 1.8V, 3.3V, etc.). * **Protection Circuitry:** It includes comprehensive safety features: * **OCP:** Over-Current Protection. * **OTP:** Over-Temperature Protection. * **SCP:** Short-Circuit Protection. * **UVLO:** Under-Voltage Lockout. * **Control Pins:** * **Enable (EN):** Allows the module to be turned on or off remotely. * **Power Good (PG):** An open-drain output that signals when the output voltage is within the regulated window. --- ### 3. Application Use Cases Due to its 8A current rating and tiny footprint, this part is ideal for: * **FPGA & DSP Power:** Providing high-current, low-voltage cores for processors. * **Industrial Automation:** Point-of-Load (PoL) regulation in compact PLC modules. * **Telecom Equipment:** High-density networking gear where airflow and space are limited. * **Distributed Power Architectures:** Converting 12V bus voltages down to logic levels. --- ### 4. Thermal Management Note While the module is highly efficient, delivering 8A from a 7x7mm package generates concentrated heat. Designers should ensure: 1. **Sufficient Copper Pour:** Use multiple thermal vias to connect the GND pads to internal PCB ground planes. 2. **Airflow:** In high-ambient temperature environments, forced air cooling may be required to maintain the 8A rating without thermal throttling.
