MPQ8633AGLE-Z
SHARAXA
MPQ8633A waa isku-dhafan oo dhamaystiran, soo noqnoqoshada sare, beddelaadaha buck-ka.Waxay bixisaa xal aad isku dhafan si loo gaaro ilaa 12A wax soo saarka hadda oo ka sarreeya sahayda sahayda ballaaran oo leh culeys aad u fiican iyo nidaaminta xariiqda.MPQ8633A waxay ku shaqeysaa si hufan marka loo eego baaxadda culeyska hadda jira ee wax soo saarka.
MPQ8633A waxay qabataa habka xakamaynta joogtada ah ee joogtada ah ee wakhtiga (COT) kaas oo bixiya jawaab celin degdeg ah oo fududaysa xasilinta loop.
Inta jeer ee hawlgalka si fudud ayaa loo dejiyay 600kHz, 800kHz, ama 1000kHz oo leh qaabaynta MODE, taasoo u oggolaanaysa inta jeer ee MPQ8633A inay sii ahaato mid joogto ah iyada oo aan loo eegin tamarta wax-gelinta/soo-saarka.
Kor-u-qaadka korantada wax-soo-saarka waxaa gacanta ku haya saacad 1ms gudaha ah.Waxa lagu kordhin karaa iyada oo lagu daro capacitor TRK/REF.Digniinta koronto-furan ee wanaagsan (PGOOD) waxay tusinaysaa wax-soo-saarku inuu ku dhex jiro baaxadda korantada ee magaca.PGOOD waxaa lagu xayiray ilaa 0.7V oo leh koronto dibadda ah marka sahayda wax gelinta ay ku guuldareysato inay awood u yeelato MPQ8633A.
Astaamaha ilaalinta oo si buuxda isugu xidhan waxa ka mid ah ilaalinta xad dhaafka ah (OCP), ilaalinta korantada ka badan (OVP), ilaalinta korantada ka yar (UVP), iyo ilaalinta heerkulka xad dhaafka ah (OTP).
MPQ8633A waxay u baahan tahay tirada ugu yar ee diyaarka ah, heerka caadiga ah, qaybaha dibadda waxaana lagu heli karaa xirmo QFN 3mm x 4mm ah.
