1. Taw qhia;
Hloov fais fab mov muaj qhov pom tseeb zoo xws li kev siv hluav taws xob tsawg, kev ua haujlwm siab thiab ntim me me. Nws tau siv dav hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Raws li cov zis voltage stabilizing tswj hom ntawm Circuit Court, hloov fais fab mov yuav muab faib ua peb hom: mem tes dav modulation (PWM), mem tes zaus modulation (PFM) thiab mem tes tus nqi modulation (PWM). Raws li hom kev sib tw, kev hloov hluav taws xob tuaj yeem muab faib ua tus kheej-zoo siab hom thiab lwm yam zoo siab, Cov hloov hluav taws xob hloov hluav taws xob tau piav qhia hauv kab lus no yog pulse width modulation (PWM). Nws yog qhov zoo siab hloov pauv hluav taws xob, uas tso tawm 12V DC tswj qhov hluav taws xob feem ntau siv hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab cov zis ntsuas tam sim no yog 6A. Nws yog tsim rau DC input fais fab mov ntawm LCD TV nyob rau hauv 32 nti.
2 、 Kev piav qhia ntawm kev tsav tsheb ntawm kev hloov fais fab adapter;
Tus tsav nti ob2269 siv nyob rau hauv lub zog hloov pauv tau piav qhia hauv tsab xov xwm no tau txais cov qauv tsim tshwj xeeb, uas yog lub zog hluav taws xob muaj txiaj ntsig zoo thiab tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg coob coob.
Ob2269 txais yuav cov qauv tsim qauv tam sim no thiab muaj cov yam ntxwv hauv qab no;
▲ kev siv hluav taws xob qis qis: kev tsim hluav taws xob qis qis ua haujlwm tsis tuaj yeem tsuas yog ua rau tag nrho cov kab ke yooj yim kom paub txog cov lus pom zoo kawg ntawm Lub Chaw Haujlwm Saib Xyuas Hluav Taws Xob Hauv Ntiaj Teb tsis muaj kev thauj khoom.
▲ kev ua haujlwm tsis muaj suab nrov: suab nrov yuav tsis tshwm nyob rau hauv lub teeb load thiab tag nrho load. Kev tsim kho kom zoo tuaj yeem ua rau lub kaw lus ua haujlwm ntsiag to hauv txhua lub xeev ua haujlwm.
▲ qis pib tam sim no: VIN / VDD pib tam sim no tsawg li 4ua, uas tuaj yeem txo qhov poob ntawm qhov pib ntawm qhov system thiab txo lub sijhawm pib ntawm qhov system.
▲ qis ua haujlwm tam sim no: qhov ua haujlwm tam sim no yog kwv yees li 2.3ma, uas tuaj yeem txo qhov poob ntawm lub cev thiab txhim kho kev ua haujlwm ntawm lub cev.
▲ ua nyob rau hauv OCP cov nyiaj them: lub built-in OCP kev them nyiaj ua haujlwm ua rau OCP nkhaus ntawm lub kaw lus zoo li nyob rau hauv tag nrho cov voltage ntau yam tsis tau nce tus nqi, thiaj li mus txhim kho tus nqi kev ua tau zoo ntawm lub system.
▲ muaj nuj nqi tiv thaiv lub suab: nws muaj kev tiv thaiv overvoltage muaj nuj nqi (OVP), dhau qhov ntsuas kub tiv thaiv kev ua haujlwm (OTP), kev tiv thaiv hluav taws xob tiv thaiv hluav taws xob (UVLO) thiab tso zis ntau dhau kev tiv thaiv kev ua haujlwm (OLP), ua ke nrog kev tiv thaiv lub suab.
▲ MOSFET soft drive: nws tuaj yeem txhim kho EMI ntawm lub cev.
2269 cov yam ntxwv ntawm lub tshuab built-in: nws tuaj yeem txo EMI thiab txo EMI.
