MCP1790T-5002E/DBVAO Frequently Asked Questions (FAQs)

  • Microchip provides a recommended PCB layout in the MCP1790T datasheet, which includes guidelines for component placement, thermal vias, and copper pours. Additionally, it's recommended to follow general high-frequency PCB design practices, such as using a solid ground plane, minimizing trace lengths, and using bypass capacitors.
  • The output capacitor selection depends on the specific application requirements, such as output voltage ripple, transient response, and ESR. A general guideline is to choose a capacitor with a low ESR (less than 100 mΩ) and a capacitance value between 10 μF to 100 μF. It's also recommended to use a capacitor with a voltage rating that exceeds the output voltage of the regulator.
  • The maximum input voltage for the MCP1790T-5002E/DBVAO is 6.5V, as specified in the datasheet. Exceeding this voltage may cause damage to the device or affect its performance. It's recommended to ensure that the input voltage is within the specified range to ensure reliable operation.
  • The MCP1790T-5002E/DBVAO has a built-in overcurrent protection feature that limits the output current to a maximum of 1.5A. To implement overcurrent protection, you can use an external current sense resistor and a comparator to monitor the output current. When the current exceeds the desired limit, the comparator can trigger a shutdown signal to the regulator.
  • The thermal derating for the MCP1790T-5002E/DBVAO is specified in the datasheet as 1.5A at 25°C, with a derating of 5.5 mA/°C above 25°C. This means that the maximum output current decreases as the ambient temperature increases. It's essential to consider thermal derating when designing the system to ensure reliable operation.
