MCP1631-E/SS Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements.
  • To ensure stability, ensure that the output capacitor has a low ESR, the input capacitor is properly sized, and the feedback network is properly compensated.
  • The maximum output current capability of the MCP1631-E/SS is 1A, but it can be limited by the thermal performance of the package and the PCB design.
  • Yes, the MCP1631-E/SS can be used in a synchronous buck configuration, but it requires an external FET driver and a low-side FET.
  • The output voltage can be adjusted by changing the resistor divider ratio in the feedback network, or by using an external voltage reference.
