♠ LM5176 55-V Wide VIN Synchronous 4-switch Buck-boost Controller
I-LM5176 iyisilawuli se-DC/DC esishintshashintshayo esine-switch-switch esikwazi ukulawula i-voltage ephumayo, ngaphezulu, noma ngaphansi kwe-voltage yokufaka. I-LM5176 isebenza phezu kwebanga elibanzi lokufaka lamandla kagesi elingu-4.2 V kuya ku-55 V (60-V absolute maximum) ukuze isekele izinhlelo zokusebenza ezihlukahlukene.
I-LM5176 isebenzisa ukulawula kwemodi yamanje kokubili kuzindlela ze-buck kanye ne-boost yokusebenza kumthwalo ophakeme nokulawulwa komugqa. Ifrikhwensi yokushintsha ihlelwa yi-resistor yangaphandle futhi ingavunyelaniswa nesignali yewashi yangaphandle.
Idivayisi iphinde ibe nomsebenzi wokuqalisa okuthambile ohlelekayo futhi inikeza izici zokuvikela ezifaka umkhawulo wamanje womjikelezo ngomjikelezo, i-Input undervoltage lockout (UVLO), i-output overvoltage protection (OVP), kanye nokuvalwa kokushisa. Ngaphezu kwalokho, i-LM5176 ihlanganisa okokufaka okumaphakathi okungakhethwa kukho noma umkhawulo wamanje, i-spectrum yokusabalalisa ongayikhetha ukuze kuncishiswe i-EMI ephezulu, kanye nokuvikelwa kwemodi ye-hiccup ongayikhetha ezimeni eziqhubekayo zokugcwala.
