MC33035P Frequently Asked Questions (FAQs)

  • A good PCB layout for the MC33035P involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to use a shielded inductor and to keep the switching node (pin 5) away from sensitive analog circuits.
  • The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value recommended in the datasheet (e.g., 10uH). Then, adjust the value based on the specific application requirements, such as output current and ripple voltage.
  • The maximum output current of the MC33035P is 3A. However, the actual output current may be limited by the input voltage, output voltage, and inductor value. It's recommended to check the thermal performance and efficiency of the converter at the desired output current.
  • The internal voltage reference of the MC33035P has a tolerance of ±2%. To compensate for this tolerance, it's recommended to use an external voltage reference or to adjust the output voltage using a resistive divider network.
  • The EN pin is used to enable or disable the converter. When the EN pin is high, the converter is enabled, and when it's low, the converter is disabled. This pin can be used to implement power sequencing, shutdown, or low-power modes.
