♠ LTC1474/LTC1475 ePhantsi eQuescent yangoku eSebenza ngokuPhezulu Iziguquli zeNyathelo ezantsi
I-LTC®Uthotho lwe-1474/LTC1475 luguqulo olusebenzayo oluphezulu olunamandla angaphakathi e-MOSFETiiswitshi ezizoba kuphela i-10µA eqhelekileyo yobonelelo lwe-DC yangokuakukho mthwalo ngelixa ugcina amandla ombane. Umfanekiso we-LTC1474isebenzisa i-logic-controlled shutdown ngelixa i-LTC1475 ibonisa iqhosha lokuvula / ukuvala.
Unikezelo oluphantsi lwangoku oludityaniswe ne-Burst Mode TM ukusebenza kwenza i-LTC1474/LTC1475 igcine ukusebenza kakuhle kwimithwalo ebanzi. Ezi mpawu, kunyengesakhono sabo se-100% somjikelo wokuyeka phakathi esikolwenikunye noluhlu olubanzi lokubonelela, yenza i-LTC1474/LTC1475ilungele imo ephakathi (ukuya kuthi ga kwi-300mA) enebhetriizicelo.
Incopho yokutshintsha yangoku inokucwangciswa komsebenzisi ngeisixhathisi sezivamvo esikhethiweyo (esimiyo ukuya kuma-325mA ubuncinci ukuba akunjaloused) ukubonelela ngeendlela ezilula zokuphucula uyilokwizicelo zangoku ezisezantsi. Incopho yolawulo lwangokuikwabonelela ngokhuseleko lwesiphaluka esifutshane kunye nokuziphatha okugqwesileyo kokuqalisa. Isixhobo sokujonga ibhetri esezantsi esihlala sisebenzaxa kucinywa kubonelelwe .
Ukufumaneka kwe-LTC1474/LTC1475 kwi-8-lead MSOPkunye neepakethe ze-SO kunye nesidingo samalungu ambalwa ongezelelweyobonelela ngesisombululo sommandla omncinci.
