Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Input Voltage Range** | 13.5V to 16.5V (Nominal 15V) | | **Output Voltage** | 5V DC | | **Output Current** | 400 mA (Max) | | **Power Rating** | 2 Watts | | **Isolation Voltage** | 1000 VDC | | **Package Type** | SIP7 (Single Inline Package) | | **Efficiency** | ~72% to 80% (typical) | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Internal Electronic Components & Architecture While the unit is an encapsulated module, its internal topology typically consists of the following functional blocks: 1. **Switching Regulator IC:** Acts as the "brain," converting the DC input into a high-frequency AC signal using pulse-width modulation (PWM) or a similar switching technique. 2. **Transformer (Isolation Barrier):** This is the core component that provides the 1000VDC galvanic isolation. It transfers energy from the primary side to the secondary side through a magnetic field, ensuring no direct electrical connection. 3. **Rectification Diode:** Converts the high-frequency AC from the transformer back into DC. 4. **Filter Capacitors:** High-quality ceramic or electrolytic capacitors used to smooth the output ripple and reduce electromagnetic interference (EMI). 5. **Feedback Loop:** Ensures the output remains stable at 5V despite fluctuations in input voltage or load changes. --- ### 3. Pin Configuration (SIP7) | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | +Vin | Positive Input Voltage | | 2 | -Vin | Negative Input (Ground) | | 4 | -Vout | Negative Output | | 6 | +Vout | Positive Output | --- ### 4. Common Applications * **Industrial Controls:** Providing isolated power to sensors and microcontrollers to prevent ground loops. * **Data Communication:** Powering RS232, RS485, or CAN bus interfaces. * **Mixed-Signal Circuits:** Separating noisy digital power supplies from sensitive analog components. * **Battery Powered Systems:** Regulating 15V battery stacks down to a stable 5V logic level. ---
