This image shows a typical application schematic for a TPS63001, which is a step-up/step-down (buck-boost) converter. It’s similar to what you’d use in your project with the TPS63051YFFR. Here's a breakdown of the connections:
  • Power Connections:
    • Connect VIN to the input voltage source. In your case, it might be a Li-Ion battery with a range of 2.5V to 5.5V.
    • Add a 10 µF capacitor between VIN and ground to smooth out input power variations.
  • Output Connections:
    • Connect VOUT to your load. You aim to achieve 3.3V @ 500mA.
    • Add a 10 µF capacitor between VOUT and ground to stabilize the output voltage.
  • Inductor:
    • Connect a 2.2 µH inductor between L1 and L2 pins.
  • Feedback and Ground Connections:
    • Feedback (FB) pin needs to be connected according to your desired output voltage configuration.
    • Connect GND and PGND pins to the ground for proper operation.
  • Additional Components:
    • Connect a 0.1 µF capacitor to VINA and ground for internal biasing.
    • A 100 kΩ resistor (R3) is connected to EN and ground.
These components support the TPS63001 in the typical application. Adjustments in resistor and capacitor values can be tweaked based on the exact output requirements and specifications of the TPS63051YFFR part.
Let me know if you have any specific areas you'd like help with in integrating the TPS63051YFFR into your project!

    A buck boost converter that can be powered from a Li-Ion battery and output 3.3V @ 500mA. Powered by the TPS63051YFFR and in the same package as a standard Adafruit buck converter.
    Expect to squeeze around 5-10% SoC from a typical Li-Ion battery.
    Input Voltage Range: 2.5V to 5.5V
