The **RTD-0505-R** is a high-performance, miniature DC/DC converter manufactured by **RECOM Power**. It belongs to the Econoline series and is specifically designed for industrial applications requiring isolation and dual output voltages. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 5V DC (Nominal) | | **Output Voltage** | ±5V DC (Dual Output) | | **Output Current** | ±200mA | | **Power Rating** | 2 Watts | | **Isolation Voltage** | 1kV DC (standard) | | **Efficiency** | 80% - 82% (Typical) | | **Package Type** | DIP14 / SMD (Surface Mount) | --- ### 2. Functional Description The RTD-0505-R serves as an unregulated power module. Its primary functions include: * **Voltage Conversion:** It takes a single 5V rail and converts it into a positive (+5V) and negative (-5V) rail. * **Galvanic Isolation:** It provides an electrical barrier between the input and output, preventing ground loops and protecting sensitive components from noise or surges. * **Dual Rail Generation:** Essential for powering operational amplifiers (Op-Amps) or analog-to-digital converters (ADCs) that require symmetrical power supplies. --- ### 3. Pin Configuration (Typical) *While you should always consult the official datasheet, the standard layout for this series is:* 1. **-Vin:** Input Ground 2. **+Vin:** Positive Input (5V) 3. **NC:** No Connection 4. **Com:** Common Ground (Output side) 5. **-Vout:** Negative Output (-5V) 6. **+Vout:** Positive Output (+5V) --- ### 4. Important Considerations for Use * **Unregulated Output:** Since this is an unregulated converter, the output voltage may fluctuate depending on the load. If the load is very light (<10%), the output voltage may rise significantly above 5V. * **Capacitive Loading:** To reduce output ripple, it is recommended to place low-ESR capacitors at the output. * **RoHS Compliance:** The "-R" suffix indicates that the part is RoHS compliant and delivered in "Reel" or "Tube" packaging suitable for automated assembly. ---
