Key Technical Specifications | Parameter | Value | | :--- | :--- | | **Input Voltage Range** | 4.5V to 5.5V DC (Nominal 5V) | | **Output Voltage** | Dual ±18V DC | | **Output Current** | ±83mA | | **Power Rating** | 3 Watts | | **Isolation Voltage** | 1000V DC | | **Package Style** | SIP8 (Single In-line Package) | | **Efficiency** | ~82% Typical | --- ### 2. Electronic Characteristics & Functionality #### A. Power Conversion and Regulation As a **DC-DC converter**, this part takes a 5V input and steps it up to a dual 18V output. It is **unregulated**, meaning the output voltage may fluctuate slightly based on the input voltage and the load applied. It is ideal for providing stable power to operational amplifiers (Op-Amps) or sensors. #### B. Isolation and Protection * **Galvanic Isolation:** It provides 1000V DC isolation between the input and the output circuits, preventing noise or high-voltage spikes from damaging sensitive components on the output side. * **Short Circuit Protection:** It features continuous short-circuit protection with auto-recovery, ensuring the device remains safe during a fault. #### C. Physical Construction (SIP8) The "RZ" suffix typically refers to the package type. The SIP8 format is a vertical mount configuration that saves significant board space compared to traditional DIP (Dual In-line) packages. --- ### 3. Pinout Configuration The AM3N-0518D-RZ utilizes a standard 8-pin SIP layout (though some pins may be omitted depending on the specific model design): | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | -Vin | Negative Input Voltage | | 2 | +Vin | Positive Input Voltage | | 3 | NC/Control | No Connection or Remote On/Off (if applicable) | | 5 | NC | No Connection | | 6 | +Vout | Positive Output Voltage (+18V) | | 7 | Common | Output Ground (0V) | | 8 | -Vout | Negative Output Voltage (-18V) | --- ### 4. Typical Applications * **Analog Circuits:** Providing the dual rails (+/- 18V) required for high-fidelity audio or instrumentation amplifiers. * **Industrial Automation:** Isolating control logic from power actuators. * **Data Acquisition:** Reducing ground loop noise in sensitive measurement systems.
