EasyCKT Buck Converter Calculator
A browser-based power-design calculator for buck-converter duty cycle, inductance, ripple, losses, operating ranges, and component limits.
Field notes
The page models an ideal continuous-conduction buck stage and lets users include high-side and low-side MOSFET resistance plus inductor DCR in the estimate. Its range explorer freezes selected L, effective C, frequency, and resistance, then recalculates duty across sampled conditions; the page explicitly cautions that this sampling does not establish a continuous-range worst case or simulate control-loop response. A design can also be saved temporarily as A and compared with a changed B state.
