The **M2AMS-15B-R** is a high-performance **Step-Up (Boost) DC-DC Converter Module** commonly used in industrial and automotive applications where a stable, higher voltage is required from a lower voltage source. Below is a detailed breakdown of its electronic specifications and features. ### 1. Technical Specifications The following table highlights the core electrical characteristics of the M2AMS-15B-R: | Parameter | Specification | | :--- | :--- | | **Input Voltage Range** | 9V to 15V DC | | **Output Voltage** | 15V DC (Fixed/Regulated) | | **Output Current** | 1.0A to 1.5A (Typical) | | **Efficiency** | ~85% - 92% | | **Package Type** | Through-hole / Encapsulated Module | | **Operating Temperature** | -40°C to +85°C | --- ### 2. Key Electronic Components & Internal Architecture While the unit is often sold as a sealed module, it contains the following essential circuitry: * **Switching Regulator IC:** The "brain" of the module that uses Pulse Width Modulation (PWM) to control the power delivery. * **Power Inductor:** Stores energy magnetically during the "on" cycle of the switch and releases it to the output during the "off" cycle to step up the voltage. * **Schottky Diode:** High-speed rectification to ensure current flows only toward the load, minimizing power loss. * **Filter Capacitors:** Input and output electrolytic or ceramic capacitors used to reduce voltage ripple and electromagnetic interference (EMI). --- ### 3. Features & Protections The "R" suffix in the part number often denotes specific compliance or a refined revision involving: 1. **Short Circuit Protection (SCP):** Automatically shuts down or limits current if the output is shorted to ground. 2. **Over-Voltage Protection (OVP):** Prevents the output voltage from spiking and damaging connected sensitive electronics. 3. **Thermal Shutdown:** Internal sensors disable the switching if the internal temperature exceeds safe operating limits. 4. **Low Ripple:** Designed to provide "clean" power suitable for analog sensors or communication equipment. --- ### 4. Typical Applications * **Automotive Systems:** Stepping up 12V battery power to a stable 15V for specialized sensors. * **Industrial Automation:** Powering 15V logic circuits from 9V or 12V BUS lines. * **Telecommunications:** Providing regulated voltage for line drivers and signal amplifiers. ---
