♠ LM5176 55-V Wide VIN Synchronous 4-switch Buck-boost Controller

I-LM5176 iyisilawuli esishintshayo se-buck-boost DC/DC 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 ku-buck kanye ne-boost izindlela zokusebenza zokulayisha okuphezulu nokulawulwa komugqa.Ifrikhwensi yokushintsha ihlelwa yi-resistor yangaphandle futhi ingavunyelaniswa nesignali yewashi yangaphandle.

Idivayisi iphinde ibe nomsebenzi wokuqalisa okuthambile ohlelekayo futhi inikeza izici zokuvikela ezihlanganisa umkhawulo wamanje womjikelezo ngomjikelezo, i-Input undervoltage lockout (UVLO), ukuvikelwa kwe-output overvoltage (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.
