♠ 2-A, UHLELO OLUNZULU LOKUFAKA, ISIguquleli ESINYATHELO ESIYA PHANSI
I-TPS5420 iyisiguquli se-PWM samanje esiphuma phambili esihlanganisa ukumelana okuphansi kohlangothi oluphezulu lwe-N-channel MOSFET. Kufakwe ku-substrate enezici ezisohlwini isikhulisi samaphutha kagesi osebenza kakhulu esihlinzeka ngokunemba kokulawulwa kwamandla kagesi ngaphansi kwezimo zesikhashana; i-undervoltage-lockout circuit ukuvimbela ukuqala kuze kube yilapho i-voltage yokufaka ifinyelela ku-5.5 V; isifunda esisethwe ngaphakathi esiqala kancane ukuze sikhawulele ukugeleza kwamanzi; kanye ne-voltage feed-forward circuit ukuze kuthuthukiswe impendulo yesikhashana.Usebenzisa iphinikhodi ye-ENA, ukuvala ukuhlinzekwa kwamandla okwamanje kuncishiswa ku-18 μA ngokuvamile. Ezinye izici zifaka amandla asebenzayo aphezulu, ukukhawulela i-overcurrent, ukuvikelwa kwe-overvoltage kanye nokuvalwa kwe-thermal. Ukuze unciphise ubunkimbinkimbi bomklamo nokubala kwengxenye yangaphandle, iluphu yempendulo ye-TPS5420 inxeshezelwa ngaphakathi.
Idivayisi ye-TPS5420 iyatholakala kuphakheji ye-SOIC yamaphini angu-8. I-TI inikeza amamojula okuhlola kanye nethuluzi lesofthiwe Yokuklama ukusiza ekufinyeleleni ngokushesha imiklamo yokuphakelwa kwamandla esebenza kahle ukuze kuhlangatshezwane nemijikelezo yokuthuthukisa imishini enolaka.
