The **RTS-1205-R** is a high-performance, isolated DC/DC converter manufactured by **RECOM Power**. It belongs to the RTS series, which is designed for board-level power distribution where space is limited and high isolation is required. --- ### ## Technical Specifications Below are the primary electrical characteristics of the RTS-1205-R: | Parameter | Value | Notes | | :--- | :--- | :--- | | **Input Voltage** | 12V DC | Nominal (Typically ±10% range) | | **Output Voltage** | 5V DC | Regulated/Unregulated (Series dependent) | | **Output Current** | 200 mA | Maximum load current | | **Power Rating** | 2 Watts | Total output power | | **Isolation Voltage** | 1 kV DC | Standard isolation (suffix -H offers more) | | **Efficiency** | 80% - 84% | Typical at full load | | **Package Type** | SIP8 | Single In-line Package (8 pins) | --- ### ## Key Electronic Components & Features #### 1. Internal Topology The device utilizes a miniature high-frequency transformer to achieve **galvanic isolation**. This physically separates the input circuit from the output circuit, preventing ground loops and protecting sensitive downstream components from voltage spikes. #### 2. Protection Mechanisms * **Short Circuit Protection:** Most models in this series include "Power Limit" or short-term short-circuit protection to prevent the internal switching transistors from overheating. * **Capacitive Load:** It is designed to handle high capacitive loads (up to 470µF), which is essential for stabilizing power in digital circuits. #### 3. Material Composition * **Case Material:** Non-conductive black plastic (UL94V-0 rated). * **Potting:** Epoxy resin used to encapsulate internal components for vibration resistance and thermal dissipation. --- ### ## Typical Applications The RTS-1205-R is commonly found in the following electronic environments: * **Industrial Controls:** Breaking ground loops in automated sensor networks. * **Data Acquisition:** Providing clean 5V power to ADC/DAC components from a 12V rail. * **Mixed Signal Circuits:** Separating noisy digital power from sensitive analog power. --- ### ## Pinout Configuration (SIP8) * **Pin 1:** +Vin (Positive Input) * **Pin 2:** -Vin (Negative Input/Ground) * **Pin 5:** -Vout (Negative Output) * **Pin 7:** +Vout (Positive Output) * *Note: Other pins may be omitted or used for specific control functions depending on the exact sub-revision.*
