Semicon Tshiab thiab Thawj IC Chip Distributor Kub Muab ICS Electronic Cheebtsam TPS54560BDDAR

1.

Lub TPS54560B yog 60V, 5A buck regulator nrog ib qho kev sib koom ua ke siab-sab MOSFET.Kev tswj hom tam sim no muab cov nyiaj them rau sab nraud yooj yim thiab hloov tau yooj yim ntawm kev xaiv.Qhov qis ripple mem tes dhia hom txo cov khoom siv tam sim no rau 146µA.Thaum EN (pab kom) tus pin raug rub qis, qhov kev kaw cov khoom siv tam sim no raug txo rau 2µA.

Lub Undervoltage thaiv tau teeb tsa sab hauv rau 4.3V tab sis tuaj yeem nce ntxiv nrog EN (pab kom) tus pin.Cov zis hluav taws xob pib-up ramp tuaj yeem tswj tau sab hauv kom tswj tau cov txheej txheem pib thiab tshem tawm overshoot.

Ib tug dav switching ntau zaus tso cai rau optimization ntawm efficiency los yog sab nraud tivthaiv loj.Cov zis tam sim no yog qhov txwv lub voj voog-los ntawm lub voj voog tam sim no.Zaus foldback thiab thermal shutdown tiv thaiv cov khoom sab hauv thiab sab nraud nyob rau hauv cov xwm txheej dhau.

Lub TPS54560B muaj nyob rau hauv 8-pin thermally enhanced HSOIC PowerPAD pob.

DC-DC yog cov lus Askiv luv luv rau tam sim no ncaj qha mus rau tam sim no, yog li DC-DC Circuit Court yog ib lub voj voog uas qee qhov DC fais fab mov hloov mus rau qhov sib txawv voltage.Qhov yooj yim circuits ntawm DC-DC converter yog ib kauj ruam-up converter, kauj ruam-down converter, thiab ib kauj ruam-up/down converter.Nyob rau hauv tib lub voj voog, yuav muaj kev ua haujlwm xws li kev nce qib rov qab thiab nce qib nce qib tib lub sijhawm.

3.

DC-DC circuits yog cais los ntawm kev ua haujlwm.

Boost converters: Circuits uas hloov cov voltages tsawg rau high voltages.

Buck converters: Circuit Court uas hloov high voltages rau tsawg voltages.

Inverters: Circuits uas hloov lub polarity ntawm voltage, muaj ob hom circuits: zoo rau qhov tsis zoo thiab tsis zoo rau qhov zoo.

Ib kauj ruam-down transformer yog xa mus rau sab input ntawm lub siab dua voltage, hloov mus rau cov zis kuj tsis tshua muaj zoo tagnrho voltage, thiaj li mus cuag lub hom phiaj ntawm kauj ruam-down transformer.Cov kauj ruam-down transformer yog ib qho tseem ceeb ntawm cov khoom siv hauv kev sib kis thiab kev hloov pauv, thiab nws cov haujlwm ib txwm muaj tsis yog tsuas yog cuam tshuam rau nws tus kheej kev nyab xeeb, thiab cov neeg siv khoom siv hluav taws xob txhim khu kev qha, tab sis tseem cuam tshuam ncaj qha rau kev ruaj ntseg ntawm lub zog hluav taws xob.Kev teeb tsa ntawm cov kauj ruam-down transformer tiv thaiv yuav tsum tau ntsib nyob rau hauv txhua rooj plaub, tsis tuaj yeem hlawv lub transformer, thiaj li hais tias qhov kev huam yuaj nthuav, cuam tshuam rau stability ntawm lub hwj chim system.Yog lub hauv paus ntsiab lus ntawm electromagnetic induction, tam sim no ib-theem ob-winding transformer ua piv txwv los piav qhia nws cov hauv paus ntsiab lus ntawm kev ua haujlwm: thaum thawj sab ntawm winding ntxiv voltage, ntws tam sim no nyob rau hauv cov tub ntxhais yuav tsim alternating flux no flux yog hu ua lub ntsiab. flux, lub ntsiab flux yuav dhau los ntawm, thawj, ib tug thib ob winding, lub winding yuav tsim induction electromotive quab yuam, yog hais tias lub thib ob sab nkag mus rau lub load, yuav muaj tam sim no ntws, tsim hluav taws xob.
