♠ Firfircoon-Clamped, Faafin-Spectrum, Qaabka hadda jira ee PWM
MAX5974_ku wuxuu bixiyaa xakamaynta galitaanka-ballaaran, firfircooni-ku-xidhan, qaabka hadda-PWM, beddelayaasha hore ee aaladaha ku shaqeeya Power-over-Ethernet (PoE) (PD). MAX5974A/MAX5974C waxay si fiican ugu habboon yihiin kala duwanaanta gelinta caalamiga ah ama isgaadhsiinta, halka MAX5974B/ MAX5974D ay sidoo kale dejiso danab hoose oo hooseeya ilaa 10.5V.
Qalabka waxaa ku jira dhowr sifooyin si kor loogu qaado hufnaanta saadka. Darawalka AUX waxa uu dib u warshadeeyaa magnetization cur kirada halkii uu ku lumin lahaa wareegga isku xidhka ee kala firdha. Wakhtiga dhiman ee la qorsheeyay ee u dhexeeya AUX iyo dareewalka weyn waxa uu ogolaanayaa beddelka eber-voltage (ZVS). Marka la eego xaaladaha culeyska iftiinka, aaladuhu waxay yareeyaan tirada wareegtada beddelka (lalaabida soo noqnoqda) si loo yareeyo khasaaraha beddelka.
MAX5974A/MAX5974B waxa ay ka kooban tahay wareegyo gaar ah si loo gaadho nidaaminta wax soo saarka iyada oo aan la isticmaalin muraayad indhaha ah, halka MAX5974C/MAX5974D ay ka faa'iidaysanayso habka jawaab celinta indhaha ee soo jireenka ah. Cod-weyneeye khalad gudaha ah oo leh tixraac 1% ah ayaa aad faa'iido u leh nashqada aan cidna lahayn, taas oo meesha ka saaraysa baahida loo qabo xakameynta shunt dibadda ah.
Qalabku waxa ay ka kooban yihiin xajin wareegga ugu sarreeya ee quudinta-horumarineed kaas oo ka dhigaya da'da xajinta voltka ugu badan inta lagu jiro xaaladaha ku-meel-gaadhka ah ee ka madaxbannaan korantada khadka, taas oo u oggolaanaysa isticmaalka MOSFET awood leh oo leh danab burbursan. Tilmaamaha soo noqnoqda ee soo noqnoqda ee barnaamijku wuxuu bixiyaa-EMI-hoose, hawlgal-faafin-spectrum.
MAX5974_ waxaa lagu heli karaa 16-pin TQFN-EP xirmo waxaana lagu qiimeeyay in lagu shaqeeyo inta u dhaxaysa -40°C to +85°C iyo -40°C to +125°C kala duwanaanshaha heerkulka.
