1.2 Basic Configuration

Figure 1-1 shows the connections for taking the buck regulator and converting it into an IBB.

The connection changes are detailed in the following list:

  1. Reassign the buck positive output as system ground.
  2. Reassign the buck regulator ground nodes as the negative output voltage node.
  3. Positive input remains the same.
