The **RTS-0515-R** is a high-quality, sub-miniature DC/DC converter manufactured by **RECOM Power**. It belongs to the RTS series, which is designed for board-level power isolation and voltage conversion in space-constrained applications. --- ### 1. General Specifications Below are the primary technical parameters for the RTS-0515-R: | Parameter | Specification | | :--- | :--- | | **Input Voltage (Nominal)** | 5V DC | | **Output Voltage** | 15V DC | | **Output Power** | 2 Watts | | **Output Current** | 133 mA | | **Isolation Voltage** | 1kV DC (standard) | | **Efficiency** | 80% - 85% (Typical) | | **Package Type** | SMD (Surface Mount Device) | --- ### 2. Key Features * **Single Output:** Provides a regulated-style (though technically an isolated, unregulated family) single 15V rail from a 5V source. * **High Power Density:** Delivers 2W of power in a very small SIP8 or SMD footprint, saving significant PCB real estate. * **Galvanic Isolation:** Provides 1kVDC isolation between the input and output, which is essential for breaking ground loops and reducing noise in sensitive circuits. * **Operating Temperature:** Typically rated for full load from -40°C to +85°C without derating. * **RoHS Compliant:** The "-R" suffix generally denotes compliance with RoHS 6/6 environmental standards and tape-and-reel packaging. --- ### 3. Pin Configuration (SMD) While you should always consult the official datasheet for your specific PCB layout, the standard RTS series SMD pinout follows this logic: | Pin # | Function | Description | | :--- | :--- | :--- | | 1 | -Vin | Ground (Input) | | 2 | +Vin | Positive Input (5V) | | 5 | -Vout | Common/Ground (Output) | | 8 | +Vout | Positive Output (15V) | | Others | NC | No Connection (used for mechanical stability) | --- ### 4. Typical Applications 1. **Industrial Control:** Providing isolated power to sensors or actuators where the ground potential might differ from the main controller. 2. **Data Acquisition:** Powering operational amplifiers or ADCs that require a 15V rail in a 5V logic system. 3. **Communication Ports:** Isolating RS232, RS485, or CAN bus interfaces to prevent voltage spikes from damaging the main MCU. --- ### 5. Design Considerations * **Capacitance:** To meet CISPR22 Class B EMC standards, an external filter (C1, L1) is usually required on the input side. * **Loading:** These converters typically require a minimum load (often 10%) to maintain voltage regulation within the specified tolerance. * **Heat Dissipation:** Although efficient, 2W in a small package generates heat. Ensure adequate airflow or copper traces to act as a heat sink.
