The **RTS-1512-R** is a high-performance, isolated DC/DC converter from RECOM Power’s RTS series. It is widely used in industrial and telecommunications applications where a 1W power output is required with specific voltage regulation and high isolation. ### 1. Key Technical Specifications The following table highlights the primary electrical characteristics of the RTS-1512-R: | Feature | Specification | | :--- | :--- | | **Input Voltage (Nominal)** | 15V DC | | **Output Voltage** | 12V DC | | **Power Rating** | 1 Watt | | **Isolation Voltage** | 1kV DC (Standard) | | **Efficiency** | 80% - 84% (Typical) | | **Package Style** | SIP8 (Single In-line Package) | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Electronic Composition and Features The device functions as an unregulated power module. Here are the core electronic aspects: * **Isolated Architecture:** It utilizes internal transformer coupling to provide 1,000V DC isolation between the input and output circuits. This is essential for breaking ground loops and protecting sensitive logic-level components from high-voltage spikes. * **Unregulated Output:** As an "unregulated" converter, the output voltage is not strictly fixed. It maintains a specific ratio to the input voltage. If the 15V input fluctuates, the 12V output will vary proportionally. * **Internal Protection:** * **Short Circuit Protection:** It typically features short-term short-circuit protection (usually limited to 1 second) to prevent catastrophic failure during a fault. * **Filtering:** The module contains internal capacitors to reduce ripple and noise, though external capacitors are often recommended for sensitive RF or precision analog circuits. * **Surface Mount/Through Hole:** The "-R" suffix usually denotes "Reel" packaging for automated SMT (Surface Mount Technology) assembly, though the RTS series is primarily known for its compact SIP8 footprint. --- ### 3. Pin Configuration (Typical SIP8) To integrate this part into a PCB, the standard pinout is as follows: | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | +Vin | Positive Input Voltage (15V) | | 2 | -Vin | Negative Input (Ground) | | 5 | -Vout | Negative Output | | 7 | +Vout | Positive Output (12V) | | 3, 4, 6 | NC | No Connection | --- ### 4. Application Use Cases * **Industrial Controls:** Providing isolated power to sensors. * **Data Interfaces:** Powering RS-232 or RS-485 transceiver chips to prevent electrical noise interference. * **Medical Equipment:** Basic isolation for non-patient-critical monitoring circuits.
