1. Determine External Components:
   • Input and output capacitors
   • Inductor
   • Resistors for feedback, limiting, and enabling.
2. Make Required Connections:
   • Connect the power input, ground, and output.
   • Additional connections for function-specific pins (enable, feedback, etc.)

1. Input Capacitor (C1) and Output Capacitor (C2):
   • Assumption: Let's assume you use 10µF capacitors.
   • Connect one side of C1 to VIN (Pin 2) and the other to GND (Pin 4).
   • Connect one side of C2 to VOUT (Pin 9) and the other to GND (Pin 4).
2. Inductor (L1):
   • Assumption: Let's assume an inductor value of 2.2µH.
   • Connect L1:1 to L1 (Pin 1).
   • Connect L1:2 to L2 (Pin 12).

3. Enable Pin:
   • Connect EN (Pin 3) to VIN (Pin 2) if you want the converter always enabled. Alternatively, connect it to a GPIO pin for microcontroller-based control.
4. Feedback Resistors (R1, R2):
   • Assumption: We will use a resistor divider network to set the output voltage to 3.3V based on the feedback reference voltage (0.8V typical for TPS63050).
   • Calculate resistor values using $V_{out} = V_{ref} \left( 1 + \frac{R1}{R2} \right)$
   • Connect R1 between VOUT (Pin 9) and FB (Pin 8).
   • Connect R2 between FB (Pin 8) and GND (Pin 4).
5. Additional Pins:
   • SS (Soft Start): Connect a capacitor (C3) here if using a soft start. If not, leave it unconnected or tie it to GND.
   • PG (Power Good): Can be connected to an indicator LED or left unconnected if not used.

• Power Section:
  • Connect C1:1 to IC1:VIN, and C1:2 to IC1:GND.
  • Connect C2:1 to IC1:VOUT, and C2:2 to IC1:GND.
  • Connect L1:1 to IC1:L1, and L1:2 to IC1:L2.
• Control and Feedback:
  • Connect EN (IC1:3) to VIN (IC1:2).
  • Connect one side of R1 to IC1:VOUT, and the other side to IC1:FB.
  • Connect R2:1 to IC1:FB, and R2:2 to IC1:GND.
