MPQ8633AGLE-Z
Kev piav qhia
MPQ8633A yog ib qho kev sib xyaw ua ke, highfrequency, synchronous puck converter.Nws muaj cov kev daws teeb meem zoo heev kom ua tiav txog li 12A cov zis tam sim no dhau ntawm cov khoom siv dav dav nrog cov khoom thauj zoo thiab cov kab kev cai.MPQ8633A ua haujlwm ntawm kev ua haujlwm siab tshaj qhov tso zis ntau yam tam sim no.
MPQ8633A txais kev them nyiaj sab hauv tsis tu ncua-rau-lub sijhawm (COT) tswj hom uas muab cov lus teb sai sai thiab ua kom lub voj ruaj khov.
Kev khiav hauj lwm zaus tau teeb tsa yooj yim rau 600kHz, 800kHz, lossis 1000kHz nrog MODE teeb tsa, tso cai rau MPQ8633A zaus nyob tas li tsis hais qhov tawm tswv yim / tso tawm voltages.
Cov zis hluav taws xob pib-up ramp yog tswj los ntawm ib qho 1ms timer.Nws tuaj yeem nce ntxiv los ntawm kev ntxiv lub capacitor ntawm TRK / REF.Qhov qhib-drain fais fab zoo (PGOOD) teeb liab qhia tias cov zis yog nyob rau hauv nws qhov nominal voltage range.Lub PGOOD yog clamped rau ib ncig ntawm 0.7V nrog rau sab nraud rub-up voltage thaum lub input mov tsis muaj hwj chim MPQ8633A.
Kev tiv thaiv tag nrho suav nrog kev tiv thaiv overcurrent (OCP), kev tiv thaiv dhau-voltage (OVP), kev tiv thaiv qis dua (UVP), thiab kev tiv thaiv overtemperature (OTP).
MPQ8633A yuav tsum muaj tsawg kawg nkaus ntawm cov khoom siv yooj yim, cov qauv, cov khoom siv sab nraud thiab muaj nyob rau hauv pob QFN 3mm x 4mm.
