♠ LM5176 55-V Wide VIN Synchronous 4-switch Buck-boost Controller
I-LM5176 sisilawuli se-synchronous four-switch buck-boost DC/DC esikwaziyo ukulawula i-voltage ephumayo, ngaphezulu, okanye ngaphantsi kombane wokungenisa. I-LM5176 isebenza kuluhlu olubanzi lwe-voltage ye-4.2 V ukuya kwi-55 V (i-60-V i-absolute absolute maximum) ukuxhasa izicelo ezahlukeneyo.
I-LM5176 isebenzisa ulawulo lwemowudi yangoku zombini kwi-buck kunye neendlela zokunyusa zokusebenza kumthwalo ophezulu kunye nokulawulwa komgca. I-frequency yokutshintsha icwangciswe ngumxhasi wangaphandle kwaye inokulungelelaniswa kwisignali yewotshi yangaphandle.
Isixhobo sikwabonisa umsebenzi olungelelanisiweyo we-soft-start-start kwaye unikezela ngeempawu zokukhusela ezibandakanya umjikelezo ngokujikelezayo ukukhawulelana kwangoku, i-input undervoltage lockout (UVLO), i-output overvoltage protection (OVP), kunye nokuvalwa kwe-thermal. Ukongeza, i-LM5176 ifaka igalelo eliphakathi elikhethiweyo okanye imveliso ekhoyo ngoku, i-spectrum yokusasazwa kokuzikhethela ukunciphisa i-EMI ephezulu, kunye nokukhusela imo ye-hiccup kwiimeko ezizinzileyo.
