♠ LM46002 3.5-V mpaka 60-V, 2-A Synchronous Step-Down Voltage Converter
LM46002 regulator ndi yosavuta kugwiritsa ntchito synchronous step-down converter DC/DC yomwe imatha kuyendetsa mpaka 2 A ya katundu wapano kuchokera pamagetsi olowera kuyambira 3.5 V mpaka 60 V. The LM46002 imapereka magwiridwe antchito, kutulutsa kulondola komanso kutsika. -kutulutsa mphamvu mu kukula kochepa kwambiri.Banja lokulirapo limapezeka muzosankha zingapo zamakono komanso 36-V yokwanira yolowera pamapaketi ogwirizana ndi pini-to-pini, kuphatikiza LM46001, LM46000, LM43603, LM43602, LM43601 ndi LM43600.Peak-currentmode control amagwiritsidwa ntchito kuti akwaniritse chipukuta misozi chosavuta komanso kuchepetsa malire apano.Zina zomwe mungasankhe monga kusintha kosinthika, kugwirizanitsa, mbendera-yabwino, mphamvu yolondola, chiyambi chofewa chamkati, chiyambi chofewa, ndi kufufuza kumapereka nsanja yosinthika komanso yosavuta kugwiritsa ntchito zosiyanasiyana.Kuwongolera kosalekeza ndi kuchepetsa ma frequency odziwikiratu pa katundu wopepuka kumapangitsa kuti kuwalako kuyende bwino.Banja limafunikira zigawo zochepa zakunja.Kukonzekera kwa pini kumalola masanjidwe osavuta, abwino kwambiri a PCB.Zida zodzitchinjiriza zikuphatikiza kutseka kwamafuta, kutsekeka kwa VCC undervoltage, malire apano ndi kuzungulira, komanso chitetezo chafupipafupi.Chipangizo cha LM46002 chikupezeka pa 16-lead HTSSOP / PWP phukusi (6.6 mm × 5.1 mm × 1.2 mm) ndi 0.65-mm kutsogolo.
