The **RTS-153.3-R** is a specific electronic component belonging to the **RTS series** of isolated DC/DC converters, manufactured by **RECOM Power**. This series is designed for applications requiring high power density and sub-miniature packaging. --- ## 1. Technical Specifications Below are the primary electrical characteristics of the RTS-153.3-R: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 15V DC (Nominal) | | **Output Voltage** | 3.3V DC | | **Output Power** | 2 Watts | | **Isolation Voltage** | 1kV DC (Standard) | | **Efficiency** | ~70% to 75% | | **Mounting Type** | Surface Mount (SMD) | | **Package Size** | Compact (DIP8 equivalent footprint) | --- ## 2. Key Features * **Galvanic Isolation:** Provides an electrical barrier between the input and output, protecting sensitive downstream components from noise or voltage spikes on the input rail. * **Power Density:** Delivers a full 2W of power in a very small physical footprint, making it ideal for space-constrained PCB designs. * **Operating Temperature:** Typically rated to operate between **-40°C to +85°C** without derating. * **Unregulated Output:** Note that the RTS series is usually **unregulated**. This means the output voltage may fluctuate slightly based on the load and input voltage variations. --- ## 3. Pinout and Internal Structure The "R" suffix typically refers to the **Reel** packaging for automated assembly, though it can sometimes indicate specific lead configurations depending on the exact sub-series. ### Internal Components: 1. **Switching Controller:** High-frequency oscillator to convert DC to AC. 2. **Transformer:** Provides the 1kV isolation and steps down the voltage. 3. **Rectification/Filtering:** Converts the AC back to a stable 3.3V DC output. --- ## 4. Typical Applications * **Industrial Controls:** Breaking ground loops in sensor networks. * **Data Acquisition:** Providing isolated power to ADC/DAC components. * **Telecom:** Small-scale power distribution on line cards. * **IGBT Gate Drivers:** Providing the necessary isolated bias voltage. ---
