♠ TPS53353 Ukusebenza okuPhezulu kwe-20-I-Synchronous Buck SWIFT™ Converter ene-Ecomode™
I-TPS53353 yimowudi ye-D-CAP™, i-20-A isitshintshi esilungelelanisiweyo esineeMOSFET ezihlanganisiweyo.Yenzelwe ukusetyenziswa lula, ukubalwa kwecandelo langaphandle eliphantsi, kunye neenkqubo zamandla ezithatha indawo.
Esi sixhobo sine-5.5-mΩ / 2.2-mΩ i-MOSFETs edibeneyo, i-1% echanekileyo, i-reference ye-0.6-V, kunye ne-integrated boost switch.Isampulu yeempawu ezikhuphisanayo zibandakanya: uluhlu lwamandla okuguqula igalelo lokuguqula ukusuka kwi-1.5 V ukuya kwi-15 V, ukubalwa kwecandelo eliphantsi kakhulu, imowudi ye-D-CAP™ yolawulo olukhawulezayo oludlulayo, ukusebenza kwemowudi yokutsiba ngokuzenzekelayo, ulawulo lokuqalisa oluthambileyo lwangaphakathi, ukuphindaphindwa okukhethiweyo. , kwaye akukho mfuneko yembuyekezo.
I-voltage ye-conversion yokuguqula i-voltage ukusuka kwi-1.5 V ukuya kwi-15 V, uluhlu lwe-voltage yokubonelela luvela kwi-4.5 V ukuya kwi-25 V, kunye noluhlu lwe-voltage ye-output luvela kwi-0.6 V ukuya kwi-5.5 V.
Isixhobo sifumaneka kwi-5-mm × 6-mm, i-22-pin ye-QFN iphakheji kwaye ichazwe ukusuka -40 ° C ukuya kwi-85 ° C.
I-TPS548B28 sisixhobo esitsha se-20A esenzelwe izicelo zeziko ledatha kunye nephakheji encinci, i-Pb-free.
