Formula

The basic formulas associated with the Inverting Buck-Boost Converter are:

• V_out = -V_in * (D / (1 – D))
• Where:
• D = Duty Cycle
• I_out = I_in * (1 – D) / D

Where V_out represents the output voltage, V_in the input voltage, I_out the output current, I_in the input current, and D the duty cycle. Understanding these formulas is essential for precise calculations.

Example Calculation

Let’s say you have:

• Input Voltage (V_in) = 12V
• Output Voltage (V_out) = -5V
• Load Current = 2A

To find the duty cycle (D):

1. Rearranging the formula gives us D = V_out / (V_out + V_in) = -5 / (-5 + 12) = 0.416.
2. For output current: I_out = 2A, we can find I_in: I_in = I_out * (D / (1 – D)) = 2 * (0.416 / 0.584) ≈ 1.43A.

This straightforward example demonstrates the power of the Inverting Buck-Boost Converter Calculator for making complex calculations manageable.
