TPS92612QDBVRQ1 PMIC - Umushoferi wa LED Ibisohoka umurongo PWM ugabanuka 150mA sot-23-5 TPS92612QDBVRQ1 Ibirango bishya byumwimerere

I. Chip ni iki

Chip, izwi kandi nka microcircuit, microchip, cyangwa umuzunguruko (IC), ni chip ya silicon irimo uruziga ruhujwe, akenshi ruto ruto kandi akenshi rugizwe na mudasobwa cyangwa ikindi gikoresho cya elegitoroniki.

Chip ni ijambo rusange kubicuruzwa bigize igice cya kabiri, umutwara wumuzunguruko uhuriweho, ugizwe na wafers.

Wafer ni agace gato cyane ka silikoni irimo uruziga rwuzuye rugizwe na mudasobwa cyangwa ikindi gikoresho cya elegitoroniki.

II.Igice cya kabiri

Imiyoboro ya semiconductor ni ibikoresho bifite imiterere yimyitwarire hagati yuwuyobora na insuliranteri mubushyuhe bwicyumba.Kurugero, diode nigikoresho gikozwe muri semiconductor.Igice cya kabiri ni ibikoresho bifite amashanyarazi ashobora kugenzurwa kandi birashobora kuva kuri insulator kugeza kubayobora.

Akamaro ka semiconductor ni nini, haba mu ikoranabuhanga ndetse no guteza imbere ubukungu.Ibyinshi mubicuruzwa bya elegitoroniki byubu, nka mudasobwa, terefone zigendanwa, hamwe na majwi bifata amajwi, bifite ibice byingenzi bifitanye isano rya hafi na semiconductor.

Ibikoresho bisanzwe bya semiconductor birimo silikoni, germanium, na gallium arsenide, hamwe na silicon niyo ifite uruhare runini mubucuruzi mubikoresho bitandukanye bya semiconductor.

Ibintu bibaho muburyo butandukanye - bikomeye, amazi, gaze, plasma, nibindi. Dukunze kuvuga ibikoresho bifite amashanyarazi mabi, nkamakara, kristu yubukorikori, amber, nubutaka, nka insulator.

Kandi ibyuma byinshi bitwara nka zahabu, ifeza, umuringa, icyuma, amabati, aluminium, nibindi byitwa abayobora.Ibikoresho bigwa hagati yabatwara na insulator birashobora kwitwa semiconductor.

III.Niki kizunguruka

Inzira ihuriweho (IC) nigikoresho gito cya elegitoroniki cyangwa ibice.

Ukoresheje inzira runaka, tristoriste, résistoriste, capacator, na inductor zisabwa mumuzunguruko hamwe ninsinga zirahuzwa hamwe, bikozwe mubice bito cyangwa uduce duto duto twa waferi ya semiconductor cyangwa insimburangingo ya dielectric, hanyuma bigashyirwa mubikonoshwa, bigahinduka a microstructure hamwe nibikorwa bisabwa byumuzunguruko.

Ibigize byose birimo byakozwe muburyo rusange, bituma ibikoresho bya elegitoronike intambwe nini iganisha kuri miniaturizasi, gukoresha ingufu nke, ubwenge, no kwizerwa cyane.Ihagarariwe mukuzunguruka ninyuguti "IC".

Abavumbuye imiyoboro ihuriweho ni Jack Kilby (imiyoboro ihuriweho na germanium (Ge)) na Robert Noyes (imiyoboro ihuriweho na silikoni (Si)).Ubwinshi bwibisabwa mu nganda za semiconductor uyumunsi ni silikoni ishingiye kumuzunguruko.

Inzira ihuriweho ni ubwoko bushya bwibikoresho bya semiconductor byakozwe mu mpera za 1950 na 1960.

Nibikorwa bya semiconductor inzira nka okiside, Photolithography, diffusion, epitaxy, hamwe no guhumeka kwa aluminium, ihuza igice cya semiconductor, résistoriste, capacator, nibindi bice bisabwa kugirango habeho uruziga rufite imirimo imwe n'imwe ihuza insinga hagati yabyo bose kuri a agace gato ka silicon, hanyuma gusudira no gufungirwa mumazu ya tube kubikoresho bya elegitoroniki.Hariho uburyo butandukanye bwo gupakira ibishishwa nka shitingi izengurutse, iringaniye cyangwa inshuro ebyiri.

Ikorana buhanga ryumuzunguruko ririmo tekinoroji yo gukora chip nubuhanga bwo gushushanya, cyane cyane mubikoresho byo gutunganya, tekinoroji yo gutunganya, gupakira no kugerageza, umusaruro mwinshi, hamwe nubushobozi bwo guhanga udushya.
