MP2491CGQB-Z Frequently Asked Questions (FAQ)

  • A good PCB layout for the MP2491CGQB-Z should include a solid ground plane, wide power traces, and a thermal relief pattern under the IC. A 4-layer PCB with a dedicated thermal layer is recommended. Refer to the application note AN-114 from Monolithic Power Systems for more details.

  • To ensure a stable and accurate output voltage, make sure to use a high-quality output capacitor with low ESR, and follow the recommended output capacitor selection guidelines in the datasheet. Additionally, ensure that the input voltage is stable and within the recommended range.

  • Although the datasheet specifies a maximum input voltage of 5.5V, it's recommended to limit the input voltage to 5V to ensure reliable operation and prevent damage to the device.

  • To calculate the power dissipation of the MP2491CGQB-Z, use the following formula: Pd = (Vin - Vout) x Iout x Efficiency. Refer to the datasheet for the efficiency curve and thermal resistance values.

  • A 10uF to 22uF ceramic capacitor with an X5R or X7R dielectric is recommended for the input capacitor. This will help to filter out noise and ensure stable operation.
