Chithunzi cha MPQ8633AGLE-Z
DESCRIPTION
MPQ8633A ndi chosinthira chokwanira, chokwera kwambiri, chosinthira buck.Imapereka yankho lophatikizika kwambiri kuti mukwaniritse zotulutsa za 12A pamitundu yambiri yolowera ndi katundu wabwino kwambiri komanso kuwongolera mizere.MPQ8633A imagwira ntchito bwino kwambiri pamitundu yambiri yotulutsa.
MPQ8633A imagwiritsa ntchito njira zowongolera zolipirira nthawi zonse (COT) zomwe zimapereka kuyankha kwakanthawi komanso kumathandizira kukhazikika kwa loop.
Mafupipafupi ogwiritsira ntchito amayikidwa mosavuta ku 600kHz, 800kHz, kapena 1000kHz ndi makonzedwe a MODE, kulola kuti ma frequency a MPQ8633A akhale osasinthasintha mosasamala kanthu za kulowetsa / zotulutsa.
Njira yoyambira yamagetsi yotulutsa imayendetsedwa ndi chowerengera chamkati cha 1ms.Itha kuwonjezeredwa powonjezera capacitor pa TRK/REF.Chizindikiro champhamvu chotseguka (PGOOD) chikuwonetsa kuti zotulutsa zili mkati mwamtundu wake wamagetsi.PGOOD imatsekeredwa mozungulira 0.7V ndi voteji yakunja yokoka pomwe cholowetsacho chikulephera kupatsa mphamvu MPQ8633A.
Zotetezedwa zophatikizika bwino zimaphatikizapo chitetezo cha overcurrent (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and overtemperature protection (OTP).
MPQ8633A imafuna zochepa zopezeka mosavuta, zokhazikika, zakunja ndipo zimapezeka mu phukusi la QFN 3mm x 4mm.
