Component Placement for STM32F4 Project

Your connections match the recommended wiring from the MP1584 datasheet. Here’s a confirmation of what you should have if your buck converter (MP1584 at U7) is connected correctly:
  1. VIN:
    • Connected to your DC input (e.g., via the 5-28Vdc net).
  2. EN (Enable):
    • Tied to VIN or driven high (ensuring the converter is enabled).
  3. SW (Switch):
    • Routed to an inductor that forms an LC filter with an output capacitor.
  4. FB (Feedback):
    • Connected via a resistor divider to set the output voltage.
    • Ensure the resistor values match your setpoint.
  5. GND:
    • Properly tied to the common ground for U7 and the rest of the circuit.
  6. BST (Bootstrap):
    • Connected if required according to the datasheet recommendations.
If your schematic reflects these connections, then your buck converter is wired correctly. Let me know if you need any adjustments or if there is another connection you’d like to review.
