    MP2459GJ-Z Typical application Circuitry


    The MP2459GJ-Z is a monolithic step-down switch mode converter that has an integrated internal power MOSFET. With exceptional load and line control, it produces a steady output current of 2A throughout a broad input supply range.

    Useful attributes: This chip features a constant frequency synchronous mode in heavy load and pulse skipping mode at light load, ensuring high efficiency across the full load range.

    Application Environments: Ideal for various applications such as network power supplies, automotive devices, and portable electronic devices owing to its compact size and high efficiency.

    Key Specifications: Operating within an input range of 4.5V to 28V, the MP2459GJ-Z boasts features like 340kHz switching frequency, an enable pin to control the on/off function, and over-current protection.

    Example Application – Network Power Supply

    1. Power Input Connectivity:

    - Input Voltage: Connect the input voltage within the range of 4.5V to 28V to pin 6 of the MP2459GJ-Z.

    - Bypass Capacitor: Integrate a bypass capacitor close to pin 6 to filter out the noise from the power supply.

    2. Ground Connection:

    - Ground Pin: Pin 2 must be connected to the system ground to establish a common electrical reference point for all circuits in the system.

    - Thermal Consideration: Ensure minimal thermal resistance between pin 2 and the system ground to facilitate efficient heat dissipation.

    3. Output Connection:

    - Load Connection: Connect pin 8 directly to the load. Place an output capacitor close to pin 8 to stabilize the output voltage.

    - Feedback: Connect a voltage divider network to pin 7 to set the desired output voltage according to the specific application needs.

    4. Enable Pin:

    - Control of On/Off Function: Utilize pin 5 to control the on/off function of the MP2459GJ-Z, ensuring energy efficiency in standby mode.

    - Pull-Up Resistor: Integrate a pull-up resistor if necessary to ensure reliable switching between on and off states.

    Design Considerations

    1. Component Ratings and Quality:

    - Verification: Verify that all components connected to MP2459GJ-Z meet the operational ratings to avoid performance issues or damage.

    - Quality Assurance: Use high-quality components to enhance the reliability and longevity of the design.

    2. Electromagnetic Interference (EMI):

    - Filtering: Integrate appropriate filtering techniques to minimize EMI, ensuring compliance with regulatory standards.

    - PCB Layout: A well-optimized PCB layout is crucial for reducing EMI and achieving optimal performance.

    3. Thermal Management:

    - Cooling Systems: Implement appropriate cooling systems to ensure that MP2459GJ-Z operates within the specified temperature limits.

    - Ambient Temperature: Consider the ambient temperature to select components that will operate effectively under expected temperature conditions.

    Effectively employing MP2459GJ-Z in a network power supply requires a well-thought-out approach to component selection, PCB layout, and thermal management. Balancing these aspects results in a design that is not only efficient but also reliable and compliant with necessary regulations and standards.
