Part Number: OPT8241
In application note, SBAA209B, how do you calculate an inductance value of 84 nH?
Ripple current: 0.25A
Voltage across the inductor?
Period of modulation: 33.3 ns
If I assume the voltage across the inductor is 1.26 V, it gives me the 84 nH, but how would I know what the voltage across the inductor is? This doesn't seem to work out for me, with two unknowns. What am I missing?
