TPS92612QDBVRQ1 PMIC – Ke alakaʻi alakaʻi alakaʻi i ka laina PWM dimming 150mA sot-23-5 TPS92612QDBVRQ1

I. He aha ke kīpē

ʻO kahi chip, i ʻike ʻia he microcircuit, microchip, a i ʻole integrated circuit (IC), he pahu silika i loaʻa i kahi kaapuni i hoʻohui ʻia, liʻiliʻi pinepine i ka nui a he hapa pinepine o kahi kamepiula a i ʻole nā ​​​​mea uila ʻē aʻe.

ʻO ka chip he huaʻōlelo maʻamau no kahi huahana semiconductor, ka mea lawe i kahi kaapuni i hoʻohui ʻia, i hana ʻia me nā wafers.

ʻO ka wafer kahi ʻāpana silika liʻiliʻi loa i loaʻa kahi kaapuni hoʻohui i ʻāpana o kahi kamepiula a i ʻole nā ​​​​mea uila ʻē aʻe.

II.He aha ka semiconductor

ʻO ka semiconductor kahi mea me nā waiwai conductive ma waena o nā mea o ka conductor a me kahi insulator ma ka wela lumi.ʻO kahi laʻana, he diode kahi mea i hana ʻia mai kahi semiconductor.ʻO ka semiconductor kahi mea nona ka conductivity uila hiki ke hoʻomalu ʻia a hiki ke loaʻa mai ka insulator a i ka conductor.

ʻO ke koʻikoʻi o nā semiconductor he mea nui, ma ke ʻano o ka ʻenehana a me ka hoʻomohala waiwai.ʻO ka hapa nui o nā huahana uila o kēia mau lā, e like me nā kamepiula, kelepona paʻalima, a me nā mea hoʻopaʻa leo kikohoʻe, ua pili ko lākou mau ʻāpana kumu i nā semiconductor.

Loaʻa nā mea semiconductor maʻamau i ke kilika, germanium, a me gallium arsenide, me ke silikona ka mea ʻoi aku ka mana o ke kālepa o nā mea semiconductor like ʻole.

Loaʻa ka mea ma nā ʻano like ʻole - paʻa, wai, kinoea, plasma, a me nā mea ʻē aʻe. Ke kuhikuhi pinepine nei mākou i nā mea me ka maikaʻi ʻole o ka uila, e like me ka lanahu, nā crystals artificial, amber, a me nā ceramics, ma ke ʻano he insulators.

A ʻo nā metala ʻoi aku ka hoʻokele e like me ke gula, ke kālā, ke keleawe, ka hao, ka tin, aluminika, a pēlā aku.Hiki ke kapa ʻia nā mea i hāʻule ma waena o nā conductors a me nā insulators he semiconductors.

III.He aha ke kaapuni hoʻohui

ʻO kahi kaapuni i hoʻohui ʻia (IC) kahi mea uila liʻiliʻi a i ʻole ʻāpana.

Me ka hoʻohana ʻana i kekahi kaʻina hana, ua hui pū ʻia nā transistors, resistors, capacitors, a me nā inductors i koi ʻia i kahi kaapuni a me nā uwila, i hana ʻia ma kahi ʻāpana liʻiliʻi a i ʻole nā ​​ʻāpana liʻiliʻi o nā wafers semiconductor a i ʻole nā ​​​​palapala dielectric, a laila hoʻopili ʻia i loko o kahi pūpū paipu, lilo i ʻāpana. microstructure me ka hana kaapuni pono.

ʻO nā mea āpau i loko o ia mea ua hoʻokumu ʻia ma ke ʻano holoʻokoʻa, e hana ana i nā ʻāpana uila i kahi hana nui i ka miniaturization, ka hoʻohana haʻahaʻa haʻahaʻa, ka naʻauao, a me ka hilinaʻi kiʻekiʻe.Hōʻike ʻia ia ma ke kaapuni e nā leka "IC".

ʻO Jack Kilby (nā kaapuni i hoʻohui ʻia e pili ana i germanium (Ge)) a me Robert Noyes (nā kaapuni i hoʻohui ʻia e pili ana i ke silicon (Si)) nā mea nāna i hoʻokumu i nā kaapuni hoʻohui.ʻO ka hapa nui o nā noi i ka ʻoihana semiconductor i kēia lā he mau kaʻa hoʻohui i hoʻokumu ʻia i ka silicon.

ʻO ke kaapuni i hoʻohui ʻia he ʻano hou o ka mea semiconductor i kūkulu ʻia i ka hopena o 1950s a me 1960s.

He kaʻina hana semiconductor e like me ka oxidation, photolithography, diffusion, epitaxy, a me ka evaporation o ka alumini, e hoʻohui i nā semiconductor, resistors, capacitors, a me nā mea ʻē aʻe e pono ai e hana i kahi kaapuni me kekahi mau hana a me nā uea hoʻohui ma waena o lākou āpau ma kahi. ʻāpana liʻiliʻi o ke kilika, a laila wili ʻia a hoʻopaʻa ʻia i loko o ka hale paipu no nā mea uila.Loaʻa nā ʻano ʻano o nā pūpū hoʻopili e like me nā pūpū poepoe, palahalaha a pālua paha.

Hoʻokomo ʻia ka ʻenehana kaapuni i hoʻohui ʻia i ka ʻenehana hana chip a me ka ʻenehana hoʻolālā, ka mea nui ma ka hana ʻana i nā mea hana, ka ʻenehana hana, ka ʻeke a me ka hoʻāʻo ʻana, ka hana nui, a me ka hiki ke hoʻolālā i nā mea hou.
