TPS92612QDBVRQ1 PMIC - Mutyairi we LED Kubuda mutsetse PWM dimming 150mA sot-23-5 TPS92612QDBVRQ1 Chitsva chitsva chaicho chaicho.

I. Chii chinonzi chip

Chip, inozivikanwawo se microcircuit, microchip, kana integrated circuit (IC), isilicon chip ine dunhu rakabatanidzwa, kazhinji diki muhukuru uye kazhinji chikamu chekombuta kana chimwe chigadziriso chemagetsi.

Chip ishoko rinozivikanwa kune semiconductor chikamu chigadzirwa, mutakuri wedunhu rakasanganiswa, iro rinoumbwa newafers.

Wafer ichidimbu chidiki chesilicon chine dunhu rakasanganiswa iro chikamu chekombuta kana imwe mudziyo wemagetsi.

II.Chii chinonzi semiconductor

Semiconductor chinhu chine conductive zvivakwa pakati peiyo conductor uye insulator pamhepo tembiricha.Semuenzaniso, diode mudziyo wakagadzirwa kubva kune semiconductor.Semiconductor chinhu chine magetsi conductivity inogona kudzorwa uye inogona kubva kune insulator kuenda kune conductor.

Kukosha kwema semiconductors kwakakura, zvese maererano nehunyanzvi uye kusimudzira hupfumi.Zvizhinji zvezvigadzirwa zvemagetsi zvemazuva ano, zvakaita semakomputa, nharembozha, uye marekodha edhijitari, zvine mayuniti azvo epakati akabatana zvakanyanya nemasemiconductors.

Zvakajairwa semiconductor zvinhu zvinosanganisira silicon, germanium, uye gallium arsenide, ine silicon iri iyo inonyanya kupesvedzera kutengeserana kwezvinhu zvakasiyana-siyana semiconductor.

Nyaya iripo mumhando dzakasiyana-siyana - yakasimba, mvura, gasi, plasma, nezvimwewo. Tinowanzo taura nezvezvinhu zvisina kunaka kwemagetsi conductivity, semarasha, artificial crystals, amber, uye ceramics, sezvidziviriro.

Uye simbi dzinoita segoridhe, sirivheri, mhangura, simbi, tini, aluminium, nezvimwe zvinonzi maconductor.Zvishandiso zvinowira pakati pemaconductor uye insulators zvinogona kungonzi semiconductors.

III.Chii chinonzi dunhu rakasanganiswa

Iyo yakabatanidzwa yedunhu (IC) chinhu chidiki chemagetsi mudziyo kana chikamu.

Uchishandisa imwe nzira, ma transistors, resistors, capacitors, uye inductors anodiwa mudunhu uye wiring akabatana pamwechete, anogadzirwa muchidimbu chidiki kana akati wandei madiki e semiconductor wafers kana dielectric substrates, uyezve akavharirwa muchubhu shell, inova microstructure nebasa rinodiwa redunhu.

Zvose zviri mukati maro zvakave zvakarongeka zvakaumbwa pamwe chete, zvichiita kuti zvikamu zvemagetsi zvive danho guru kune miniaturization, kushandiswa kwesimba shoma, njere, uye kuvimbika kwepamusoro.Inomiririrwa mudunhu nemavara "IC".

Vakagadzira maseketi akabatanidzwa vaive Jack Kilby (maseketi akabatanidzwa akavakirwa pagermanium (Ge)) naRobert Noyes (maseketi akabatanidzwa akavakirwa pasilicon (Si)).Ruzhinji rwezvishandiso muindasitiri yesemiconductor nhasi silicon-based integrated circuits.

Iyo yakabatanidzwa yedunhu rudzi rutsva rwe semiconductor mudziyo wakagadzirwa mukupera kwema1950 nema1960.

Iyo semiconductor yekugadzira maitiro senge oxidation, photolithography, diffusion, epitaxy, uye evaporation yealuminium, iyo inobatanidza semiconductors, resistors, capacitors, uye zvimwe zvikamu zvinodiwa kugadzira dunhu rine mamwe mabasa uye waya dzinobatanidza pakati pavo vese pa chidimbu chesilicon, uye chakabva chasungirirwa uye chakavharirwa muchubhu imba yemidziyo yemagetsi.Kune akasiyana mafomu ekurongedza mabhomba akadai seakatenderedza makungu, flat kana kaviri inline.

Yakabatanidzwa tekinoroji tekinoroji inosanganisira tekinoroji yekugadzira chip uye tekinoroji yekugadzira, kunyanya mukugadzira michina, kugadzira tekinoroji, kurongedza uye kuyedza, kugadzirwa kwehuwandu, uye kugona kugadzira hunyanzvi.
