♠ LM5176 55-V Wide VIN Synchronous 4-hloov Buck-boost Controller
LM5176 yog ib qho synchronous plaub-hloov buck-boost DC / DC maub los muaj peev xwm tswj tau cov zis hluav taws xob ntawm, saum toj no, lossis qis dua qhov input voltage. Lub LM5176 ua haujlwm dhau qhov kev tawm tswv yim dav dav ntawm 4.2 V rau 55 V (60-V qhov siab tshaj plaws) los txhawb ntau yam kev siv.
LM5176 siv tam sim no-hom tswj ob qho tib si nyob rau hauv phaw thiab boost hom kev lag luam rau superior load thiab kab kev cai. Lub zaus hloov pauv yog programmed los ntawm ib qho kev tiv thaiv sab nraud thiab tuaj yeem synchronized rau lub teeb liab moos sab nraud.
Cov cuab yeej tseem muaj qhov programmable soft-start function thiab muaj kev tiv thaiv nta xws li lub voj voog los ntawm lub voj voog tam sim no txwv, input undervoltage lockout (UVLO), tso zis overvoltage tiv thaiv (OVP), thiab thermal shutdown. Tsis tas li ntawd, LM5176 nta qhov kev xaiv nruab nrab ntawm kev tawm tswv yim lossis tso tawm tam sim no txwv, kev xaiv kis tau los txo qis EMI, thiab xaiv hom kev tiv thaiv hiccup nyob rau hauv cov xwm txheej hnyav dhau.
