The **MGFS154805-R** is a high-reliability, isolated DC-DC converter manufactured by **Cosel**. It is part of the MGFS series, known for its compact size (1x1 inch footprint) and high power density. --- ## 1. Technical Specifications Below is a summary of the core electronic characteristics of the MGFS154805-R: | Parameter | Specification | | :--- | :--- | | **Series** | MGFS (Isolated DC-DC) | | **Nominal Power** | 15 Watts | | **Input Voltage Range** | 18V to 76V DC (Wide Input) | | **Output Voltage** | 5V DC | | **Output Current** | 3.0 Amperes | | **Isolation Voltage** | 1,500V DC (1 minute) | | **Efficiency** | 89% (Typical) | | **Operating Temp** | -40°C to +85°C | --- ## 2. Key Electronic Features The device incorporates several specialized electronic circuits to ensure stability and protection: * **Wide Input Range (4:1):** Unlike standard 2:1 converters, this part can handle large fluctuations in supply voltage, making it suitable for 24V or 48V battery-powered systems. * **Built-in Protections:** * **Overcurrent Protection (OCP):** Automatically recovers when the fault condition is removed. * **Overvoltage Protection (OVP):** Protects the load from voltage spikes. * **Thermal Protection:** Shuts down the unit if internal temperatures exceed safety limits. * **Remote ON/OFF:** Allows the converter to be controlled by an external logic signal to save power. * **Voltage Trimming:** The output voltage can be adjusted (typically ±10%) using an external resistor. * **Six-sided Shielding:** The case is metallic and grounded to reduce Electromagnetic Interference (EMI). --- ## 3. Pin Configuration The MGFS154805-R uses a standard through-hole pinout for PCB mounting: | Pin Number | Function | Description | | :--- | :--- | :--- | | 1 | +VIN | Positive Input | | 2 | -VIN | Negative Input (GND) | | 3 | RC | Remote Control (ON/OFF) | | 4 | +VOUT | Positive Output | | 5 | TRM | Output Voltage Adjustment (Trim) | | 6 | -VOUT | Negative Output | --- ## 4. Typical Application Circuit When integrating this part, it is standard practice to include external capacitors to reduce ripple and noise: ```markdown [Input Source] ---- [Cin] ---- (+VIN) [MGFS154805-R] (+VOUT) ---- [Cout] ---- [Load] (-VIN) (-VOUT) ``` * **Cin:** Typically a 22μF–100μF electrolytic capacitor to stabilize input voltage. * **Cout:** A ceramic or tantalum capacitor to smooth output ripples.
