MPS3646 Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the MPS3646 is 42V, although the recommended maximum operating voltage is 36V to ensure reliable operation.

  • To ensure stability, it's essential to follow the layout guidelines provided in the datasheet, use a sufficient output capacitor, and add a compensation network (e.g., a resistor and capacitor) between the COMP and FB pins.

  • The minimum ESR required for the output capacitor is 10mΩ, although a lower ESR can help improve the regulator's stability and transient response.

  • Yes, the MPS3646 is rated for operation up to 150°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.

  • The power dissipation of the MPS3646 can be calculated using the formula: Pd = (VIN - VOUT) x IOUT + (VIN x IGND) + (VOUT x IQUIESCENT), where IGND is the ground current and IQUIESCENT is the quiescent current.
