Power management Chip IC ndiye malo operekera mphamvu ndi ulalo wazinthu zonse zamagetsi ndi zida, zomwe zimayang'anira kusintha, kugawa, kuzindikira ndi ntchito zina zowongolera mphamvu yofunikira, ndi chida chofunikira kwambiri pazamagetsi ndi zida zamagetsi.Panthawi imodzimodziyo, ndi chitukuko cha intaneti ya Zinthu, mphamvu zatsopano, luntha lochita kupanga, robotics ndi madera ena omwe akutuluka ntchito, msika wapansi wa tchipisi tating'onoting'ono tamagetsi unayambitsa mwayi watsopano wachitukuko.Zotsatirazi ndikudziwitsani za kagawidwe, kugwiritsa ntchito ndi kuweruza kwa luso la kasamalidwe ka IC chip.
Power management chip classification
Mwa zina chifukwa cha kuchuluka kwa ma ics oyang'anira mphamvu, ma semiconductors amagetsi adasinthidwa kukhala ma semiconductors owongolera mphamvu.Ndi chifukwa chakuti mabwalo ambiri ophatikizika (IC) m'malo operekera magetsi, anthu amangoyang'ana kasamalidwe kamagetsi kuti atchule gawo lamakono laukadaulo wamagetsi.Power management semiconductor mu gawo lotsogola la IC kasamalidwe ka mphamvu, ikhoza kufotokozedwa mwachidule monga 8 zotsatirazi.
1. AC/DC kusinthasintha kwa IC.Lili ndi otsika ma voltage control circuit ndi high voltage switching transistor.
2. DC/DC kusintha kwa IC.Mulinso zowongolera zolimbikitsa / zotsika pansi, ndi mapampu opangira.
3. mphamvu factor control PFC pretuned IC.Perekani gawo lolowera mphamvu ndi ntchito yowongolera mphamvu.
4. pulse modulation kapena pulse amplitude modulation PWM/PFM control IC.Makina osinthira ma pulse frequency modulation ndi/kapena pulse wide modulation controller poyendetsa ma switch akunja.
5. linear modulation IC (monga linear low voltage regulator LDO, etc.).Mulinso owongolera amtsogolo ndi oyipa, ndi machubu osinthira ma voltage otsika a LDO.
6. Kuthamanga kwa batri ndi kasamalidwe ka IC.Izi zikuphatikiza kuyitanitsa kwa batri, chitetezo ndi ma ics owonetsera mphamvu, komanso ma "smart" ma ics a batri a kulumikizana kwa data ya batri.
7. Hot swap board control IC (osakhudzidwa ndi kuyika kapena kuchotsa mawonekedwe ena panjira yogwirira ntchito).
8. MOSFET kapena IGBT kusintha ntchito IC.
Pakati pa maics oyang'anira mphamvu awa, ma voltage regulation ICS ndi omwe akukula mwachangu komanso opindulitsa kwambiri.Ma ics osiyanasiyana oyang'anira mphamvu nthawi zambiri amalumikizidwa ndi mapulogalamu angapo okhudzana, kotero mitundu yambiri ya zida zitha kulembedwa pamapulogalamu osiyanasiyana.
Awiri, kugwiritsa ntchito mphamvu kasamalidwe Chip
Kukula kwa kasamalidwe ka mphamvu ndikokulirakulira, kuphatikiza osati kungosintha kwamagetsi kodziyimira pawokha (makamaka DC kupita ku DC, komwe ndi DC/DC), kugawa ndi kuzindikira kwamagetsi odziyimira pawokha, komanso njira yophatikizira yosinthira mphamvu ndi kasamalidwe ka mphamvu.Chifukwa chake, gulu la chip kasamalidwe ka mphamvu limaphatikizanso zinthu izi, monga linear power chip, voltage reference chip, switching power chip, LCD driver chip, LED driver chip, voltage discovery chip, batire charging management chip ndi zina zotero.
Ngati kamangidwe ka dera kwa magetsi ndi phokoso mkulu ndi ripple kuponderezedwa, anapempha kuti atenge yaing'ono PCB m'dera (mwachitsanzo, mafoni ndi m'manja zinthu zamagetsi m'manja), magetsi dera saloledwa ntchito inductor (monga foni yam'manja) , ma calibration osakhalitsa ndi mphamvu zotulutsa boma zimayenera kudziyang'anira ntchito, kutsika kwapansi kumafunika voteji stabilizer ndi mphamvu yake yochepa, mzere wa mtengo wotsika ndi njira yosavuta, Ndiye magetsi a mzere ndiye chisankho choyenera kwambiri.Mphamvu yamagetsi iyi imaphatikizapo matekinoloje otsatirawa: kulondola kwa voteji, magwiridwe antchito apamwamba, amplifier yaphokoso yotsika, chowongolera chotsitsa chamagetsi, chotsika chotsika.
Kuphatikiza pa chipangizo chosinthira mphamvu, chipangizo chowongolera mphamvu chimaphatikizanso chipangizo chowongolera mphamvu ndicholinga chogwiritsa ntchito mphamvu moyenera.Monga NiH batire wanzeru kuthamangitsa Chip, lithiamu ion batire ndi kutulutsa kasamalidwe chip, lithiamu ion batire pa voteji, pa panopa, pa kutentha, yochepa dera chitetezo Chip;Mu mzere magetsi ndi zosunga zobwezeretsera batire kusintha kasamalidwe Chip, USB mphamvu kasamalidwe Chip;Pampu yolipiritsa, magetsi a LDO amitundu yambiri, kuwongolera motsatizana mphamvu, chitetezo chambiri, kuchuluka kwa batri ndi kasamalidwe kamphamvu kachipangizo kamphamvu, ndi zina zambiri.
Makamaka pamagetsi ogula.Mwachitsanzo, kunyamula DVD, foni yam'manja, digito kamera ndi zina zotero, pafupifupi 1-2 zidutswa mphamvu kasamalidwe Chip angapereke zovuta Mipikisano njira magetsi, kuti ntchito ya dongosolo bwino.
Chachitatu, kasamalidwe kamphamvu ka boardboard kachipangizo kabwino kapena koyipa koganiza bwino
Motherboard power management chip ndi yofunika kwambiri mavabodi, tikudziwa kuti chigawo ntchito kukwaniritsa chikhalidwe ichi, chimodzi ndi voteji, china ndi mphamvu.Motherboard power management chip imayang'anira mphamvu yamagetsi ya gawo lililonse la chipboardboard.Bolodi yoyipa ikayikidwa patsogolo pathu, titha kuzindikira kaye chipangizo chowongolera mphamvu cha boardboard ndikuwona ngati chip chili ndi magetsi otulutsa.
1) Choyamba pambuyo poti chipangizo chowongolera mphamvu cha mainboard chathyoledwa, CPU sigwira ntchito, ndiye kuti, sipadzakhala kutentha pambuyo poti mainboard ikuyendetsedwa pa CPU, nthawi ino mutha kugwiritsa ntchito popi ya diode ya mita. kuyesa kukana kwa koyilo ya inductor ndi pansi ngati mita ikugwetsa mtengo wotsutsa umakwera kutsimikizira kuti chipangizo chowongolera mphamvu ndi chabwino, m'malo mwake, pali vuto.
2) Ngati mphamvu yamagetsi yamagetsi ndi yabwinobwino koma voteji ya chipangizo chowongolera mphamvu si yachilendo, mutha kuyang'ana kaye voteji ya FIELD effect chubu G pole, monga kulabadira kukana kosiyanasiyana, ndikutsimikizira kuti chip kasamalidwe ka mphamvu ndi cholakwika.
