WSP4888 Lua N-Alāvai 30V 9.8A SOP-8 WINSOK MOSFET
Fa'amatalaga Lautele
O le WSP4888 o se transistor maualuga ma se fausaga sela mafiafia, lelei mo le faʻaaogaina i le synchronous buck converters. O loʻo faʻaalia le RDSON sili ona lelei ma totogi o faitotoa, ma avea ai ma filifiliga sili mo nei talosaga. E le gata i lea, o le WSP4888 e fetaui ma manaʻoga RoHS ma Green Product ma e sau ma se faʻamaoniga 100% EAS mo galuega faʻalagolago.
Vaega
Advanced Trench Technology e fa'aalia ai le maualuga o le cell density ma le maualuga o le totogi o le faitoto'a, fa'aitiitia ai le aafiaga CdV/dt. O a matou masini e sau ma le 100% EAS fa'amaonia ma filifiliga fa'alelei.
O a matou MOSFET e faʻatautaia faiga faʻatonutonu lelei ina ia mautinoa latou te ausia tulaga maualuga o alamanuia. O iunite taʻitasi e faʻataʻitaʻiina maeʻaeʻa mo le faʻatinoga, tumau ma le faʻamaoni, faʻamautinoaina se ola umi o oloa. O lona mamanu gaoa e mafai ai ona tatalia tulaga ogaoga o galuega, fa'amautinoaina le fa'aogaina o meafaigaluega.
Tau fa'atauva'a: E ui lava i lo latou tulaga maualuga, oa tatou MOSFET e matua'i fa'atauva'a le tau, e maua ai se fa'aola taua tele e aunoa ma le fa'afefeina o le fa'atinoga. Matou te talitonu e tatau i tagata fa'atau uma ona maua le avanoa i oloa e sili ona lelei, ma o la matou ta'iala tau e atagia ai lenei tautinoga.
Feso'ota'iga lautele: O a tatou MOSFET e fetaui ma le tele o faiga fa'aeletoroni, ma avea ai ma filifiliga sili mo tagata gaosi ma tagata fa'aoga. E tu'ufa'atasia fa'atasi i faiga o lo'o iai, fa'aleleia le fa'atinoga atoa e aunoa ma le mana'omia o ni suiga tetele o mamanu.
Talosaga
Talosaga Maualuluga Point-of-Load Synchronous Buck Converter mo le faʻaogaina i le MB / NB / UMPC / VGA system, Networking DC-DC Power Systems, Uta Suiga, E-sikareti, Uaea Uea, Motors, Drones, Mea Faʻafomaʻi, Taʻavale Taʻavale, Pule , Oloa Fa'atekinolosi, Laiti Meafaigaluega Fale, ma Fa'atau Fa'aeletonika.
