♠ LM46002 3.5-V ukuya 60-V, 2-A Synchronous Inyathelo-Down phantsi Voltage Converter
Umlawuli we-LM46002 yi-synchronous step-down-down-down converter ekulula ukuyisebenzisa ukuya kuthi ga kwi-2 A yomthwalo wangoku ukusuka kwi-voltage yegalelo ukusuka kwi-3.5 V ukuya kwi-60 V. I-LM46002 ibonelela ngokusebenza ngokugqwesileyo, ukuchaneka kwemveliso kunye nokuhla. I-voltage ephumayo kwisisombululo esincinci kakhulu.Intsapho eyandisiweyo ifumaneka kwiinketho ezahlukeneyo zomthwalo wangoku kunye ne-36-V ephezulu yokufakelwa kwamandla ombane kwiipakethi ezihambelana ne-pin-to-pin, kuquka i-LM46001, LM46000, LM43603, LM43602, LM43601 kunye ne-LM43600.I-Peak-currentmode control isetyenziselwe ukufezekisa imbuyekezo ye-controlloop elula kunye nomjikelo-ngomjikelo wangoku umda.Iimpawu ezikhethwayo ezifana ne-programmable switching frequency, ulungelelwaniso, iflegi elungileyo, ukuchaneka kukuvumela, isiqalo esithambileyo sangaphakathi, ukuqala okuthambileyo okwandisiweyo, kunye nokulandelela kubonelela ngeqonga eliguquguqukayo nelilula lokusebenzisa uluhlu olubanzi lwezicelo.Ukuqhuba okungapheliyo kunye nokunciphisa amaza okuzenzekelayo kwimithwalo ekhanyayo kuphucula ukusebenza kakuhle komthwalo wokukhanya.Intsapho ifuna amacandelo ambalwa angaphandle.Ulungiselelo lwe-Pin luvumela i-PCB elula, eyiyeyona ilungileyo.Iimpawu zokukhusela zibandakanya ukuvala i-thermal, i-VCC i-undervoltage lockout, umda wangoku we-cycle-by-cycle, kunye ne-output-short-circuit protection.Isixhobo se-LM46002 sifumaneka kwi-16-lead HTSSOP / PWP iphakheji (6.6 mm × 5.1 mm × 1.2 mm) kunye ne-0.65-mm ehamba phambili.
