Boost Converter Calculator

Find the output voltage of a step-up boost converter.

Output voltage (V) 12.5

Formula: V_out = V_in ÷ (1 − D)

Step-by-step with your numbers:

1. Values used:

2. Input voltage = 5 V

3. Duty cycle = 60 %

5. Output voltage = 12.5V

Did we solve your problem today?

A boost converter steps voltage up using an inductor and switching.

The math behind it

For continuous conduction, V_out = V_in ÷ (1 − D). As D approaches 1, the output rises sharply.

5 V at 60% duty → 12.5 V.

Why can't D reach 100%?

The output would theoretically go to infinity; real circuits limit the duty cycle.
