♠ LM5176 55-V Yagutse VIN Ihuza 4-ihindura Buck-kuzamura Umugenzuzi
LM5176 ni syncronine enye-buck-kuzamura DC / DC umugenzuzi ushoboye kugenzura ingufu zisohoka kuri, hejuru, cyangwa munsi yinjiza voltage. LM5176 ikora hejuru yumurongo mugari wa voltage ya 4.2 V kugeza 55 V (60-V ntarengwa ntarengwa) kugirango ishyigikire porogaramu zitandukanye.
LM5176 ikoresha igenzura-ryuburyo bwombi haba muri buck no kuzamura uburyo bwimikorere kugirango umutwaro urenze kandi ugenzure umurongo. Guhindura inshuro byateguwe na rezistor yo hanze kandi irashobora guhuzwa nikimenyetso cyamasaha yo hanze.
Igikoresho kirimo kandi porogaramu yoroheje-itangira imikorere kandi itanga uburyo bwo kurinda harimo cycle by-cycle igabanya imipaka, kwinjiza undervoltage lockout (UVLO), kurinda ibicuruzwa birenze urugero (OVP), no guhagarika ubushyuhe. Mubyongeyeho, LM5176 iragaragaza impuzandengo yikigereranyo cyinjiza cyangwa ibisohoka bigarukira, gukwirakwiza gukwirakwiza kugabanya impanuka ya EMI, hamwe no kurinda uburyo bwa hiccup muburyo bwo kurenza urugero.
• Umutekano wimikorere-Birashoboka - Inyandiko ziboneka zifasha igishushanyo mbonera cyumutekano
• Induction imwe ya buck-kuzamura umugenzuzi kugirango azamuke / intambwe-hasi DC / DC ihinduka
• VIN yagutse: 4.2 V (2.5 V hamwe kubogama) kugeza kuri 55 V (60 V ntarengwa)
• IJWI RYoroshye: 0.8 V kugeza 55 V.
• VUTS kurinda gato
• Impinduka nziza cyane-kuzamura inzibacyuho
• Guhindura inshuro nyinshi
• Guhitamo inshuro nyinshi guhuza no gutandukana
• Kwinjiza 2-A MOSFET abashoferi b'irembo
• Umuzenguruko-by-cycle ntarengwa ntarengwa hamwe na hiccup
• Ibyifuzo byinjira cyangwa ibisohoka impuzandengo igezweho
• Porogaramu ishobora kwinjiza UVLO no gutangira byoroshye
• Imbaraga Nziza nibisohoka birenze urugero
• Iraboneka muri paki ya HTSSOP-28 na QFN-28
• Kora igishushanyo cyihariye ukoresheje LM5176 hamwe na WEBENCH Power Designer
