Kusintha kowongolera ndi njira yabwino kwambiri yosinthira voteji imodzi ya DC kukhala voteji ina ya DC.Ndipo kudutsa ma topology onse osakhala akutali a DC/DC - buck, boost, buck-boost ndi inverting - timakuthandizani kukulitsa magwiridwe antchito a IC yowongolera ma voltage anu ndi makina osinthira a DC/DC, ma module amagetsi ndi owongolera.
Kuchuluka kwa mphamvu
Mphamvu zambiri, malo ochepa a bolodi.Zowonetseredwa ndi banja la SWIFT ™ buck regulator, mbiri yathu ya zida zamphamvu zolimba kwambiri ndizophatikizika, zokhala ndi magwiridwe antchito apamwamba komanso kuthekera kwapakali pano pakuyika kophatikizika, kowonjezera kutentha.
Owongolera osinthika kwambiri ndi njira yabwino yopangira mphamvu zama digito apamwamba kwambiri monga ma FPGA ndi mapurosesa.Gwiritsani ntchito chida chathu chophatikizira purosesa kuti mupeze zinthu zabwino kwambiri zomwe zikugwirizana ndi FPGA kapena purosesa yanu.
Mtengo wotsika kwambiri wa EMI
Kuchepetsa kusintha kowongolera EMI kumatha kukhala vuto lalikulu kwa opanga ambiri opanga magetsi.Zipangizo zokhala ndi matekinoloje ochepetsera a EMI zimasunga nthawi yopangira ndikukuthandizani kutsatira mfundo zovuta monga CISPR 25 Class-5.Yang'anani zinthu zathu zomwe zili pansipa za zosinthira zaposachedwa kwambiri komanso zabwino kwambiri za DC/DC pakuchita kwa EMI.
Low quiescent current (IQ)
DC/DC switching regulators okhala ndi ultra-low quiescent panopo amawonjezera mphamvu yamagetsi ndikuwonjezera moyo wa batri m'mapulogalamu onyamula komanso oyendetsedwa ndi batire.Pezani zida zina zotsika kwambiri za IQ pazosintha zathu za switcher pansipa.
Phokoso lochepa & zolondola
Owongolera osinthira amafunikira LDO ya post-regulator kuti ipangitse mphamvu ma ADC ndi ma AFE apamwamba.Koma ndi phokoso labwino kwambiri lamakampani komanso magwiridwe antchito, TPS62912 ndi TPS62913 zimakupatsani mwayi wochotsa phokoso lotsika LDO pamapulogalamu ambiri, kupulumutsa malo a PCB ndi mtengo wonse ndikuwongolera magwiridwe antchito.
