The image you've provided is a schematic diagram for a TPS63020-based buck-boost converter circuit. It shows the necessary external components around the TPS63020 IC to create a 3.3V output voltage from an input voltage range of 2.5V to 5.5V, capable of supplying up to 2A.
Here's a brief explanation of the components and their connections:
  • Input Capacitors (C1 and C3): These capacitors are placed at the input to filter high-frequency noise and provide a stable voltage source.
  • Inductors (L1 and L2): These are part of the switching circuit that allows the converter to step up or down the input voltage to maintain a stable output voltage.
  • Feedback Resistors (R1 and R2): These create a voltage divider that sets the output voltage by feeding a portion of the output back to the feedback pin (FB) of the IC.
  • Resistor R3 and Capacitor C4 (Loop Compensation): These components are for loop compensation to ensure stability in the feedback control loop of the converter.
  • Output Capacitors (C2): Provides output filtering to smooth out the voltage and current provided to the load.
  • Bypass Capacitor (C3): Additional bypassing/stabilization for the IC.
  • Power Good Output: This is an open-drain output that can be connected to an LED or another status indicator to reflect when the output voltage is within a specific range.
To translate this schematic into connections on your project in Flux, start by identifying the components by their designator numbers and then connecting the pins accordingly. If you've already added components like the TPS63020 IC to your project, proceed with additional components and wire them as shown in the image. If the components aren't added yet, you'll have to add them first.
You should also be aware that the values of the external components such as resistors and capacitors may need to be adjusted based on your specific application requirements beyond the typical values shown in this schematic.
