♠ TPS65251 4.5-V mpaka 18-V Zolowetsa, Zapamwamba-Pakalipano, Zolumikizana Pansi Pansi Zitatu Za Buck Zokhala Ndi FET Yophatikizidwa
TPS65251 ili ndi zosintha zitatu zofananira zosakanikirana bwino kwambiri.Ma converters adapangidwa kuti azisavuta kugwiritsa ntchito pomwe amapatsa wopanga mwayi woti awonjezere kugwiritsa ntchito kwawo molingana ndi zomwe akufuna.
Otembenuza amatha kugwira ntchito mu 5-, 9-, 12- kapena 15-V machitidwe ndipo ali ndi ma transistors ophatikizika amphamvu.Mphamvu yotulutsa imatha kukhazikitsidwa kunja pogwiritsa ntchito chogawira chopinga pamtengo uliwonse pakati pa 0.8 V ndi pafupi ndi zolowera.Kusintha kulikonse kumathandizira pini yomwe imalola kuchedwetsa kuyambika kwa zolinga zotsatizana, pini yoyambira yofewa yomwe imalola nthawi yoyambira yofewa posankha capacitor yoyambira, ndi pini yamalire (RLIMx) yomwe imathandizira wopanga kusintha malire apano. posankha chopinga chakunja ndikuwongolera kusankha kwa inductor.Ulamuliro wamakono wamakono umalola kubwezera kwa RC kosavuta.
Ma frequency osinthira osinthika amatha kukhazikitsidwa ndi chopinga chakunja cholumikizidwa ndi pini ya ROSC kapena amatha kulumikizidwa ndi wotchi yakunja yolumikizidwa ndi pini ya SYNC ngati pakufunika.Zowongolera zosinthira zidapangidwa kuti zizigwira ntchito kuchokera ku 300 kHz mpaka 2.2 MHz.180 ° kunja kwa gawo logwira ntchito pakati pa Buck 1 ndi Buck 2, 3 (Buck 2 ndi 3 kuthamanga mu gawo) kumachepetsa zofunikira zosefera.
