♠ I-LTC1474/LTC1475 Iziguquli Zezinyathelo Eziphansi Zamanje Ezisebenza Kakhulu Ezisebenza Kakhulu
I-LTC®Uchungechunge lwe-1474/LTC1475 luyiziguquli ezisebenza kahle kakhulu ze-stepdown ezinamandla angaphakathi e-P-channel MOSFETamaswishi adonsa kuphela i-10µA evamile enikezela nge-DC okwamanjeakukho mthwalo ngenkathi kugcinwa i-voltage ephumayo.Idatha ye-LTC1474isebenzisa ukuvala shaqa okulawulwa ngokunengqondo kuyilapho i-LTC1475 ifaka inkinobho yokuvula/ukuvala.
Ukunikezwa okuphansi kwamanje okuhambisana nokusebenza kwe-Burst Mode TM kwenza i-LTC1474/LTC1475 igcine ukusebenza kahle okuphezulu phezu kohlu olubanzi lwemithwalo.Lezi zici, kanyengamandla abo omjikelezo womsebenzi ongu-100% kwabashiya phakathi abaphansikanye nobubanzi bokuhlinzekwa kokufakwayo okubanzi, yenza i-LTC1474/LTC1475ilungele ukusebenza kwebhethri okumaphakathi (kufika ku-300mA).izicelo.
I-peak switch current iyahleleka nomsebenzisi nge-isivikeli senzwa ongasikhetha (okuzenzakalelayo kuya ku-325mA ubuncane uma kungenjaloused) ukuhlinzeka ngezindlela ezilula zokuthuthukisa umklamongezinhlelo zokusebenza zamanje eziphansi.Ukulawula kwamanje okuphezulufuthi inikeza ukuvikeleka kwesifunda esifushane kanye nokuziphatha okuhle kakhulu kokuqalisa.Isitholi sebhethri eliphansi esihlala sisebenzauma kuvalwe kunikezwa .
Ukutholakala kochungechunge lwe-LTC1474/LTC1475 ku-MSOP ehamba phambili engu-8kanye namaphakheji e-SO kanye nesidingo sezingxenye ezimbalwa ezengeziwehlinzeka ngesixazululo sendawo esincane.
