MP2491CGQB-Z Typical application Circuitry

MP2491CGQB-Z

The MP2491CGQB-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 1A throughout a broad input supply range.

Utilization Situations: The MP2491CGQB-Z is designed for various applications where high efficiency, compact size, and precise voltage regulation are essential, including distributed power systems, networking systems, and FPGA, DSP, and ASIC power supplies.

Key Parameters: The device operates at a 2MHz switching frequency and has an input voltage range of 4.5V to 36V. It is extremely efficient and has strong protection measures like cycle-by-cycle current limiting and thermal shutdown.

Application - FPGA Power Supply

1. Power Source Connection:

- Pin 3 (IN): Connect the input power source to pin 3. Ensure the voltage is within the 4.5V to 36V range to properly power the MP2491CGQB-Z.

- Bypass Capacitor: A bypass capacitor should be close to pin 3 to filter the input noise for stable operation.

2. Grounding:

- Pin 4 (GND): Connect this pin to the system ground. For this pin, a sturdy ground plane aids in heat dissipation and reduces noise.

- Ground Plane: Ensure a solid and wide ground plane to minimize ground noise and enhance thermal performance.

3. Output Power:

- Pin 6 (SW): The switch node, connected to the internal power MOSFET, should connect to the load (e.g., FPGA) through an inductor and capacitor to form the LC filter.

- LC Filter: Choose the inductor and capacitor values carefully to optimize the transient response and minimize the output voltage ripple.

4. Feedback Loop:

- Pin 1 (FB): Connect a resistor divider network from the output to this pin to set the output voltage level. Ensure stability in the feedback loop for accurate voltage regulation.

- Loop Compensation: To obtain the required transient response and stability, adjust the loop compensation components.

Design Considerations

1. Inductor Selection:

- Inductor Value: The choice of inductor affects the converter's performance. Balance between size, cost, and efficiency while considering the operating frequency and current.

- Saturation Current: The inductor's saturation current should be higher than the peak current to avoid performance degradation.

2. Output Capacitor:

- Capacitor Value and ESR: Select the output capacitor considering the Equivalent Series Resistance (ESR) and the desired output voltage ripple.

- Placement: Place the output capacitor close to the load to reduce the effects of parasitic inductance and resistance.

3. Thermal Management:

- Heat Dissipation: Design the PCB to enhance heat dissipation, considering factors like ambient temperature and airflow.

- Thermal Pads and Vias: Utilize thermal pads and vias to enhance heat dissipation and ensure the MP2491CGQB-Z operates within the safe temperature range.

4. Protection Features:

- Utilize Built-in Protections: Leverage the integrated cycle-by-cycle current limiting and thermal shutdown to enhance system reliability.

- Additional Protections: Consider implementing additional protections like input over-voltage and under-voltage lockout as needed.

Leveraging the MP2491CGQB-Z for power supply applications requires a detailed focus on component selection, layout design, thermal management, and protective features. Every design aspect should aim for optimal performance, efficiency, and reliability to harness the full potential of this versatile converter chip.
