# Switching-inductor current ripple
# Scope: Ideal CCM buck inductor ripple at supplied switching frequency.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

input = 24 V
output = 12 V
inductance = 100 uH
frequency = 100000 Hz

duty := output/input
ripple := (input-output)*duty/(inductance*frequency) [A]

check ripple budget: ripple <= 1 A

scenario alternative: input = 19.2 V
