Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 5V DC (Nominal) | | **Output Voltage** | ±9V DC (Dual Output) | | **Output Current** | ±111 mA | | **Power Rating** | 2 Watts | | **Isolation Voltage** | 3000 VDC | | **Efficiency** | ~75% - 80% | | **Package Style** | SIP7 (Single In-line Package) | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Electronic Component Breakdown The device functions as a **Switched-Mode Power Supply (SMPS)**. Inside its small casing, it contains several critical electronic stages: #### A. Input Filtering To minimize electromagnetic interference (EMI) and handle input voltage ripples, the device includes internal bypass capacitors. For sensitive circuits, an external capacitor (typically 4.7µF to 10µF) is recommended at the input. #### B. The Switching Controller & Transformer 1. **Oscillator/Switch:** Converts the 5V DC input into a high-frequency AC signal. 2. **Isolation Transformer:** The "H30" in the part number signifies **3000VDC isolation**. This magnetic component transfers energy from the input to the output without a direct electrical connection, protecting the rest of the system from surges or noise. #### C. Output Rectification & Regulation 1. **Diodes:** High-speed Schottky diodes rectify the high-frequency AC back into DC. 2. **Dual Output Logic:** The "D" in the part number indicates **Dual Output**. It provides both +9V and -9V relative to a common ground, which is essential for powering Op-Amps or bipolar sensors. --- ### 3. Pin Configuration (SIP7) | Pin # | Function | Description | | :--- | :--- | :--- | | 1 | +V Input | Positive Supply Input (5V) | | 2 | -V Input | Ground/Negative Input | | 4 | -V Output | Negative Voltage Output (-9V) | | 5 | Common | Output Ground (0V) | | 6 | +V Output | Positive Voltage Output (+9V) | --- ### 4. Typical Applications * **Operational Amplifiers:** Providing symmetrical ±9V rails for high-fidelity audio or signal processing. * **Industrial Controls:** Isolating control logic from noisy actuator power. * **Data Acquisition:** Reducing ground loop noise in sensitive sensor measurements. ---
