MCP1631-E/ST Frequently Asked Questions (FAQ)

  • The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input ripple and improve output stability.

  • To ensure the MCP1631-E/ST operates within its SOA, follow the guidelines in the datasheet for input voltage, output current, and power dissipation. Additionally, ensure that the device is properly heat-sinked and that the PCB layout is designed to minimize thermal resistance.

  • The EN (Enable) pin is used to enable or disable the device. When the EN pin is pulled high, the device is enabled and operates normally. When the EN pin is pulled low, the device is disabled and enters a low-power shutdown mode.

  • The output voltage of the MCP1631-E/ST can be adjusted by using an external resistor divider network connected to the FB (Feedback) pin. The resistor values can be calculated using the formula provided in the datasheet.

  • The maximum output current capability of the MCP1631-E/ST is 1.5A. However, the actual output current capability may be limited by the input voltage, output voltage, and power dissipation of the device.
