# Buck-converter first sizing
# Scope: Ideal continuous-conduction buck conversion; losses omitted.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

input = 24 V
output = 12 V
load = 2 A

duty := output/input
inputCurrent := output*load/input [A]

check buck duty physical: duty <= 1

scenario alternative: input = 19.2 V
