Ive Igikorwa-gifunze, Ikwirakwizwa-Ikirangantego, Ibigezweho-Uburyo bwa PWM
MAX5974_ itanga igenzura ryagutse-ryinjiza-voltage, ikora-ifunze, uburyo-bwa PWM, abahindura imbere muri Power-over-Ethernet (PoE) ibikoresho bikoresha amashanyarazi (PD).MAX5974A / MAX5974C ikwiranye neza no kwinjiza isi yose cyangwa itumanaho, mugihe MAX5974B / MAX5974D nayo yakira voltage ntoya kugeza kuri 10.5V.
Ibikoresho birimo ibintu byinshi kugirango byongere umusaruro.Umushoferi wa AUX yongeye gukoresha ubukode bwa magnetizing cur aho kuyitesha mumashanyarazi atandukanye.Porogaramu ishobora gupfa hagati ya AUX na shoferi nyamukuru yemerera guhinduranya zero-voltage (ZVS).Mugihe cyumucyo-umutwaro, ibikoresho bigabanya guhinduranya ubwisanzure (inshuro inshuro) kugirango igabanye igihombo.
MAX5974A / MAX5974B iranga umuzunguruko udasanzwe kugirango ugere kumusaruro udakoresheje optocoupler, mugihe MAX5974C / MAX5974D ikoresha uburyo bwa gakondo bwo gutanga ibitekerezo.Ikosa ryimbere ryimbere hamwe na 1% ryingirakamaro ni ingirakamaro cyane mugushushanya kutavanze, bivanaho gukenera kugenzura ibintu hanze.
Ibikoresho biranga ibiryo bidasanzwe-byimbere byinshingano-cycle clamp ituma clamp ntarengwa ya volt yimyaka mugihe cyigihe gito itagendeye kumurongo wumurongo wa voltage, itanga ikoreshwa ryingufu MOSFET hamwe na voltage yo hasi yo kumeneka.Porogaramu ishobora gukoreshwa inshuro nyinshi itanga EM-yo hasi, ikwirakwiza-ibikorwa.
MAX5974_ iraboneka mumyaka 16 ya pin ya TQFN-EP kandi irapimwe kugirango ikore hejuru ya -40 ° C kugeza kuri + 85 ° C na -40 ° C kugeza kuri + 125 ° C.
