### 2. Key Internal Electronic Parts
The module is an "All-in-One" solution, meaning several discrete components are integrated into a single compact housing:
* **Integrated Transformer:** Provides the magnetic coupling required for electrical isolation between the input and output stages.
* **Switching Controller:** A high-frequency PWM (Pulse Width Modulation) IC that manages power delivery and stabilizes output.
* **Rectifier Diodes:** Convert the high-frequency AC from the transformer back into DC.
* **Capacitive Filters:** Internal ceramic capacitors (MLCC) to reduce ripple and noise on the output line.
* **Protection Circuitry:** Often includes Short Circuit Protection (SCP) and Thermal Shutdown features to prevent damage during fault conditions.
