Ua tib zoo saib xyuas cov teeb meem hauv qab no thaum xaiv lub tshuab hluav taws xob hloov pauv:
1. Cov xwm txheej zoo tshaj plaws rau kev siv LDO Thaum lub ripple thiab suab nrov nyob rau hauv cov zis voltage yuav tsum tau tshwj xeeb me me, qhov sib txawv ntawm cov tswv yim thiab cov zis voltage tsis loj, thiab cov zis tam sim no tsis ntau tshaj 100mA, kev siv micro-power , low-dropout (LDO) linear regulators yog Qhov tsim nyog tshaj plaws, haum rau feem ntau cov khoom siv portable.
2. Thaum yuav tsum muaj lub hwj chim tsis zoo, sim siv lub twj tso kua mis. Portable twj feem ntau xav tau lub zog tsis zoo. Txij li qhov xav tau tam sim no tsis loj, nws yog qhov yooj yim tshaj plaws los siv lub twj tso kua mis IC los ua ib qho hluav taws xob inversion circuit. Charge twj IC nrog LDO linear regulator.
3. Tsis txhob mus nrhiav kev ua haujlwm siab, muaj lub zog ICs ntawm cov khoom siv tshiab kawg. Qhov tseeb ntawm cov khoom siv hluav taws xob IC feem ntau yog ± 2 feem pua rau ± 4 feem pua, thiab qhov raug siab tuaj yeem ncav cuag ± 0.5 feem pua rau ± 1 feem pua. Qhov tseeb tsim nyog yuav tsum raug xaiv raws li qhov yuav tsum tau ua ntawm lub voj voog, kom cov nqi tsim khoom tuaj yeem raug txo. Tus nqi ntawm cov cuab yeej siv nrog kev ua tiav ntau dua, thiab cov cuab yeej tsis muaj lub hwj chim tawm haujlwm lossis cov khoom tsis muaj microprocessor (μP) lossis microcontroller (μC) tsis tas yuav xaiv lub cuab yeej nrog lub hwj chim-tawm los yog kev ua haujlwm. tso zis fais fab mov ua hauj lwm raws li txoj cai teeb liab, uas tsis tsuas yog txo tus nqi thiab me me.
4. Tsis txhob "lub laub nees loj" Peb qhov tseem ceeb ntawm lub hwj chim IC yog cov input voltage VIN, cov zis voltage Vo thiab qhov siab tshaj plaws tso zis tam sim no Iomax. Xaiv raws li kev ua haujlwm tam sim no ntawm cov khoom: nws yog qhov tsim nyog dua tias qhov siab tshaj plaws ua haujlwm tam sim no yog 70 feem pua rau 90 feem pua ntawm cov zis siab tshaj plaws tam sim no Iomax ntawm lub hwj huam mov IC.
