To design a buck-boost converter with the TPS63051YFFR for a 3.3V output at 500mA, powered by a Li-ion battery, follow these steps:

Step 1: Gather Components

IC: TPS63051YFFR
Inductor: Choose an inductor with appropriate current ratings, e.g., 2.2μH
Capacitors: Output and input capacitors with appropriate voltage ratings, e.g., 10μF
Resistors: For feedback, if needed for setting the output voltage
Diode: Schottky diode, if necessary according to the reference design
Miscellaneous: Headers, connectors, battery holder, etc.

Step 2: Connections

Referencing the datasheet for the TPS63051YFFR, let's define the connections:

Power Connections:
- Connect your Li-ion battery positive terminal to the input capacitor $C1:1$ and then to the VIN pin of TPS63051YFFR.
- Connect the ground of your Li-ion battery to the GND pin of TPS63051YFFR and to the other pin of the input capacitor $C1:2$ .
Inductor and Capacitors:
- Connect the inductor $L1:1$ between the VOUT pin and the SW pin of TPS63051YFFR.
- Connect the output capacitor $C2:1$ between the VOUT pin and ground $C2:2$ .
Feedback Resistors:
- If the output voltage needs to be set (usually these are internal for this IC), otherwise, connect these as per the design example in the datasheet.
- Connect a resistor $R1$ between the VOUT pin and FB pin of the TPS63051YFFR.

Detailed Connections

Power Input from Battery:
- Connect Battery:Positive to $C1:1$
- Connect $C1:2$ to TPS63051YFFR:VIN
- Connect Battery:Negative to TPS63051YFFR:GND and C1:GND
Inductor Connection:
- Connect TPS63051YFFR:SW to $L1:1$
- Connect $L1:2$ to TPS63051YFFR:VOUT
Output Capacitor:
- Connect $C2:1$ to TPS63051YFFR:VOUT
- Connect $C2:2$ to TPS63051YFFR:GND
Feedback Resistor (if needed):
- Connect $R1:1$ to TPS63051YFFR:VOUT
- Connect $R1:2$ to TPS63051YFFR:FB
Ground Connections:
- Ensure all grounds (battery, input capacitor, output capacitor) are connected together.

Step 3: PCB Layout

On the PCB side:

Place components close to the IC to reduce parasitic inductance.
Use wide traces for power and ground lines to handle the current.
Route the feedback trace away from noisy signals to maintain stability.

Step 4: Verify and Validate

Simulate the circuit if possible.
Prototype and measure the output voltage and current to ensure it meets specifications.

Schematic Summary

Power Input:
- Connect Battery:Positive to $C1:1$
- Connect $C1:2$ to TPS63051YFFR:VIN
- Connect Battery:Negative to TPS63051YFFR:GND and C1:GND
Inductor and Output Capacitor:
- Connect TPS63051YFFR:SW to $L1:1$
- Connect $L1:2$ to TPS63051YFFR:VOUT
- Connect $C2:1$ to TPS63051YFFR:VOUT
- Connect $C2:2$ to TPS63051YFFR:GND
Feedback Resistor:
- Connect $R1:1$ to TPS63051YFFR:VOUT
- Connect $R1:2$ to TPS63051YFFR:FB

Final Notes

Consult the TPS63051YFFR datasheet for specific recommendations and values.
Be sure to consider the thermal design and ensure proper heat dissipation in your layout.
