MPQ8633AGLE-Z
INKCAZO
I-MPQ8633A idityaniswe ngokupheleleyo, i-highfrequency, i-synchronous buck converter.Inika isisombululo esihlangeneyo sokufikelela kwi-12A yemveliso yangoku phezu koluhlu olubanzi lokubonelela kunye nomthwalo obalaseleyo kunye nolawulo lomgca.IMPQ8633A isebenza ngempumelelo ephezulu ngaphezulu koluhlu olubanzi lwemveliso yangoku.
I-MPQ8633A ithatha imo yolawulo yangaphakathi yembuyekezo yangaphakathi (COT) ebonelela ngempendulo yexeshana ekhawulezayo kwaye ilula ukuzinzisa loop.
I-frequency yokusebenza imiselwe ngokulula kwi-600kHz, 800kHz, okanye i-1000kHz kunye noqwalaselo lwe-MODE, evumela ukuba i-MPQ8633A i-frequency ihlale ingatshintshi kungakhathaliseki ukuba igalelo / imveliso yombane.
Irempu yokuqalisa umbane wemveliso ilawulwa sisibali-xesha sangaphakathi se-1ms.Inokwandiswa ngokongeza i-capacitor kwi-TRK / REF.Isiginali ye-open-drain power (i-PGOOD) ibonisa imveliso ingaphakathi koluhlu lwamandla ombane.I-PGOOD ibotshelelwe malunga ne-0.7V kunye ne-voltage yangaphandle yokutsalwa xa unikezelo lwegalelo lusilela ukunika amandla i-MPQ8633A.
Iimpawu ezidityanisiweyo zokukhusela zibandakanya ukukhuselwa ngokugqithisileyo (OCP), ukukhuselwa kwe-voltage (OVP), ukukhuselwa ngaphantsi kwe-voltage (UVP), kunye nokukhusela ukushisa (OTP).
I-MPQ8633A idinga inani elincinci lezinto ezifumanekayo, eziqhelekileyo, zangaphandle kwaye zifumaneka kwi-QFN 3mm x 4mm iphakheji.
