Kev taw qhia luv luv ntawm lub xov tooj ntse tswj fais fab IC (1)
Nov 19, 2019| Shenzhen Shenchuang Hi-tech Electronics Co., Ltd (SChitec) yog lub tuam txhab ua haujlwm siab uas tshwj xeeb hauv xov tooj accessories ntau lawm thiab muag khoom. Peb cov khoom tseem ceeb muaj xws li kev mus ncig, chargers tsheb, USB cables, fais fab nyiaj hauv tuam txhab nyiaj thiab lwm yam khoom siv digital.Tag nrho cov khoom muaj kev nyab xeeb thiab txhim khu kev qha, nrog cov cim styles.products dhau daim ntawv pov thawj xws li CE, FCC, ROHS, UL, PSE, C-Tick, thiab lwm yam. , Yog tias koj txaus siab rau, koj tuaj yeem tiv tauj ceo@schitec.com ncaj qha.

Kev taw qhia luv luv ntawm lub xov tooj ntse tswj fais fab IC (1)
Tam sim no, muaj hwj chim tswj IC (PMIC), lossis chav tswj fais fab (PMU), nyob rau hauv feem ntau cov xov tooj smartphones. Nws yog ib hom tshwj xeeb lub hom phiaj kev sib koom ua ke, uas nws txoj haujlwm yog los tswj cov khoom siv hluav taws xob rau lub ntsiab system. PMU ua haujlwm feem ntau ntawm cov khoom siv hluav taws xob thiab qee qhov chaw ua haujlwm, xws li interface lossis suab. Qee lub khw lag luam ua lag luam analog semiconductor muab kev kho, ib nrab kho thiab / lossis cov khoom siv txheem ntawm PMU. Lub zog tswj IC qauv yog qhia hauv qab no.
1. Tsis tshua muaj siab sib txawv linear regulator
Nyob rau hauv feem ntau cov xov tooj ntse, 5-12 ywj siab low-voltage differential linear regulators (LDOS) feem ntau yog siv. Xws li ntau tus LDOS tsis txhais tau hais tias tib tus naj npawb ntawm qhov ntsuas hluav taws xob muaj nyob hauv lub davhlau ya nyob twg, tab sis vim tias LDOS kuj tau siv los ua rau / tawm keyboards nrog qee yam PSRR los tiv thaiv lub suab sib txuas. Feem ntau ntawm LDOS tau koom ua ke hauv PMU, tab sis qee zaum ib tus neeg sib cais LDOS tau siv. Qhov no feem ntau yog vim qhov kev teeb tsa / thaiv ntawm PCB, qee qhov tshwj xeeb (xws li hluav taws xob tswj oscillator) yog cov suab nrov dhau lawm, lossis siv los tsav qee qhov tsis yog qauv, xws li cov koob yees duab digital, thiab lwm yam.
Tau ntev, 150maldo encapsulated hauv SOT-23 yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv hluav taws xob sib cais (sib cais). Tam sim no, qee cov khoom siv IC tshiab tau txais kev ntim khoom tshiab, tshiab submicron ua cov thev naus laus zis thiab cov txheej txheem tsim qib siab, uas tuaj yeem muab kev ua tau zoo dua nrog qhov me me. Tam sim no peb tuaj yeem tau txais SOT-23 pob ntawm ib leeg 300maldo lossis ob lub 150maldo li, lossis micro SC-70 pob ntawm ib leeg 120almado, nrog cov qauv qauv thiab cov suab nrov qis (RMS tus nqi 10 μ V, 85dbpsrr) version khoom siv. Tsis tas li ntawd, cov pob qib siab tshaj nti (UCSP ™) muab qhov me me tshaj plaws, thaum QFN pob tso cai rau cov nti loj tshaj plaws los nruab rau hauv 3mm × 3mm cheeb tsam cov pob yas, thaum muab lub peev xwm hloov hluav taws xob ntau dua. QFN pob tuaj yeem ua tiav LDO tam sim no ntau dua, thiab ntau dua LDOS tuaj yeem ntim rau hauv txhua pob, uas tuaj yeem muaj 3-5 LDOS, uas txo qhov sib txawv ntawm cov txheej txheem sib cais thiab PMU.
Kev tswj hwm hluav taws xob tau dhau los ua qhov kev sib tw zoo tshaj plaws, tshwj xeeb tshaj yog hauv kev sib txuas lus, suav thiab kev siv tshuab. Nrog rau kev txhim kho txuas ntxiv ntawm FPGA thiab SOC, cov neeg tsim qauv ntxiv ntau qhov sib xyaw ua haujlwm sib xyaw ua haujlwm hauv cov cim txuas ntxiv, uas tuaj yeem ua tiav qhov kev ua tau zoo uas yav dhau los tsis tuaj yeem sib tw.
