Select a topology, enter your design parameters, and instantly get duty cycle, inductor, capacitor and switch current values — with full working formulas.
⚠ Disclaimer: This calculator is for educational and estimation purposes only.
All results assume Continuous Conduction Mode (CCM) and ideal component behaviour.
Real-world designs will differ due to parasitics, temperature effects, component tolerances and non-ideal switching.
Always verify with simulation (SPICE/MATLAB) and hardware testing before implementation.
