He aha ke kumu o nā mea hiki ke koho i kahi chipLako ikehuPIN?
E like me nā mīkini uila uila eʻikeʻia ana e lawelawe ana nā mea hiki ke lawelawe i nā hana maʻamauʻehā: e hoʻopiʻi ana i nā hana. I kēia lā, e pili ana wau i ka weheweheʻana i ka hana decopurling.
Nāʻano maʻamau o nā caliplings decopling
Ke hōʻike nei ke kiʻi ma luna nei i kahi papa'āpana hapa o kahi scm32 Series Microcontroller Mix e hoʻonohonoho pono ai i ka mana. Ua koi kēia mcuʻelima mau mana mana 3.3v i hāʻawiʻia e ka LDO (haʻahaʻa haʻahaʻa haʻahaʻa (haʻahaʻa haʻahaʻa haʻahaʻa), e like me ka lm1117.
No ke aha e pono ai nā koho decopling
ʻOiaiʻo RDOS maʻamau e hāʻawi pinepine i nā voltas State i hoʻohālikelikeʻiaDc-dc reders(eg, hiki i nā tps5430) E'ōlelo i kēia, kau mākou i nā cappuplings i nā capaclings kokoke i nā kiʻina o Chip a Chip. ʻO kēia mau mea hiki i nā salacors ke komoʻana i nā maʻi maʻi kiʻekiʻe mai ka hāʻawiʻana i ka mana, e hoʻopaʻa ana iā ia i ka lepo, i laila e hōʻoia i ka boc. No ka hana maikaʻi loa, pono e kauʻia nā camipling i ka wā e pili ana i ka hiki ke hiki i ka mika o Chip.
No ke aha i hoʻohana pinepineʻia ai kahi 0.1F i kahi maʻamau maʻamau?
I ka wā e hoʻopaʻa ana i ka mana kūpono,ʻike pinepine mākou i ka capacitor e like me kēia ala, ma nā haʻahaʻa haʻahaʻa, nā hana mua e like me ka kānana. Eia naʻe, e like me ka hoʻonui pinepineʻana, e lilo i ka hana inductive o ka capacitor e lilo i mea nui a me ka nui o ka nohoʻana. Ma waho aʻe o kahi paepae kiko'ī pinepine,ʻo ka kānana kānana o ka mea hiki ke hoʻopauʻia. ʻO kēia keʻano manā hana kiʻekiʻe,ʻaʻole e hana hou ka capacitor i kahi "maʻemaʻe". ʻO nā hiʻohiʻona koʻikoʻi maoli o kahi capacitor e hōʻikeʻia ma ka pihi ma lalo nei:
Mai ka pihi,ʻo ka kānana kūpono e hele ana ma ka haʻahaʻa haʻahaʻa loa o kaHE MOOLELOcurve (ka liʻiliʻi liʻiliʻi). Eia nō naʻe, e like me ka hoʻonui pinepineʻana, he 0.1μf capacitor e lilo i mea kūpono i ka hopena o kahi 0.01μF catactitor. Ma nā ala kiʻekiʻe aʻe,ʻoi aku ka nui o nā waiwai i hiki ke loaʻa (e like me, 0.001μf) e koiʻia no ka kānana maikaʻi.
Hoʻolaha: Nā Kūpepa Paterlel
E kuhikuhi i kēia palena, he nui nā hoʻolālā circuit e hoʻohana i nā koho he nui i ka paraclel me nā waiwai likeʻole. Ma ka hoʻohuiʻana i nā koho o nā waiwai o nāʻano hana likeʻole, ua hoʻonuiʻia ka nui o nā kānana i ka nui o ka nui. Hiki i kēia ala ke hana i ka hana kānana holomua ma luna o kahi ākea o nā alapine o nā alapine.
