boost inductor ripple sizing calculator online

Use boost inductor ripple sizing online for input V, output V, frequency Hz, ripple A. Ideal CCM boost with supplied inductor ripple target. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.

How to use it

Enter input V. Set output V, frequency Hz, ripple A. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
input VMain input. Positive values. 5
output VOption. Positive values. 12
frequency HzOption. Positive values. 100000
ripple AOption. Positive values. 0.5

Calculation method

inductance_H = input_V*positive(1-input_V/output_V)/(frequency_Hz*ripple_A) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply boost inductor ripple sizing to the case below, keeping the displayed units and assumptions. Ideal CCM boost with supplied inductor ripple target.

Choose the right tool

Match the topology before entering values: series and parallel networks, inverting and noninverting stages, and buck and boost converters use different equations. Component ratings, parasitics, protection and measured conditions require separate review.

Limitations and common mistakes

  • Ideal CCM boost with supplied inductor ripple target. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
