Estou ficando louco ou eles erraram?

Mensagempor Francesco » 24 Fev 2011 16:13

Pessoal, uma dúvida simples. Só para ter certeza, pois uma vírgula faz diferença.

Neste datasheet:
Na página 14, no exemplo 3 ele calcula o Cout mínimo. No exemplo, Vin=25, Vout=10 e L=150uH. O cálculo proposto é:

Cout > 13.300 * ( Vin / ( Vout * L ) )

Logo...

Cout > 13.300 * ( 25 / ( 10 * 150 ) )

O resultado deles é 22,2uF... o meu é 221,67uF.

O que é que eu fiz de errado?
