The **GS-R24F0252.0** is a specific high-efficiency voltage regulator module, part of the GS-R series manufactured by STMicroelectronics. It is designed to provide a stabilized output voltage from a wider input range, primarily used in industrial and telecommunications applications. --- ### 1. Key Technical Specifications Below are the primary electrical characteristics for the GS-R24F0252.0: | Parameter | Specification | | :--- | :--- | | **Input Voltage Range** | 9V to 40V DC | | **Output Voltage** | 5.2V DC (Fixed) | | **Output Current** | 2.5 Amps | | **Efficiency** | Up to 85% | | **Switching Frequency** | ~100 kHz | | **Isolation** | Non-isolated | | **Package Type** | SIP (Single In-line Package) or Module | --- ### 2. Internal Electronic Components The module is a "Step-Down" (Buck) switching regulator. Internally, it integrates several discrete components into a single potted housing: * **Switching Controller:** An integrated circuit (IC) that manages the Pulse Width Modulation (PWM) to regulate voltage. * **Power MOSFET:** High-speed transistor used as the primary switch to handle the input current. * **Power Inductor:** Used for energy storage during the switching cycle to smooth out the current. * **Schottky Diode:** Acts as a freewheeling diode to provide a path for the current when the MOSFET is off. * **Filter Capacitors:** Input and output capacitors to reduce electromagnetic interference (EMI) and voltage ripple. --- ### 3. Pin Configuration and Functions The module typically features a simple pinout for easy PCB integration: 1. **+Vi (Input):** Unregulated positive DC input. 2. **GND (Ground):** Common return path for both input and output. 3. **+Vo (Output):** Regulated 5.2V DC output. 4. **Inhibit (Optional):** Some versions include a pin to remotely turn the module ON or OFF. --- ### 4. Features and Protection * **Short Circuit Protection:** Automatically limits current or shuts down if the output is shorted. * **Thermal Shutdown:** Protects the internal circuitry if the module exceeds its operating temperature. * **Low Profile:** The compact design allows it to be used in space-constrained electronic racks. * **No External Heat Sink:** In many standard operating conditions, the high efficiency eliminates the need for bulky external cooling.
