♠ 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.
