Inkcazelo ye-LM5160
I-LM5160/A yi-65-V,2-A i-synchronous step-down converter kunye ne-MOSFETs edibeneyo ehlangeneyo kunye necala eliphantsi.I-adaptive ye-adaptive ye-time control scheme ayifuni imbuyekezo ye-loop kwaye ixhasa umlinganiselo ophezulu wokuhla kunye nokuphendula ngokukhawuleza okwethutyana.I-feedbackamplifier yangaphakathi igcina i-± 1% yolawulo lwe-voltage yemveliso kulo lonke uluhlu lobushushu bokusebenza.Ixesha le-Theon liyahluka ngokungafaniyo kunye ne-voltage yegalelo ekhokelela kwi-switchingfrequency phantse rhoqo.
Incopho kunye nentlambo imida imijikelezo yangoku zikhusela kwiimeko zokugcwala.I-Theundervoltage lockout (EN/UVLO) isekethe ibonelela ngokuzimeleyo igalelo elihlengahlengiswayo elingaphantsi komthamo kunye ne-hysteresis.I-LM5160/A icwangciswe ngepini ye-FPWM ukuba isebenze kwimodi yokuqhubela phambili (CCM) ukusuka kungabikho mthwalo ukuya kumthwalo opheleleyo okanye ukutshintshela ngokuzenzekelayo kwimodi ye-discontinuousconduction (DCM) kumthwalo wokukhanya ukuze usebenze kakuhle.Umsebenzi onyanzelweyo we-CCM uxhasa iziphumo ezininzi kunye nosetyenziso olulodwa lweFly-Buck kusetyenziswa i-inductor edibeneyo.
I-LM5160A yabelana ngeempawu ezifanayo kunye noqwalaselo lwepin njenge-LM5160.Ukunikezelwa kwe-bias yangaphandle kunokudibaniswa kwi-pin ye-VCC ye-LM5160A kwi-Buck kunye ne-Fly-Buckapplications.Lo mandla ongezelelweyo wehlisa ukuchithwa kwamandla e-IC kwaye uphucula ukusebenza kakuhle kwe-athigh input voltages.
