TPS54320 ndi mawonekedwe athunthu a 17-V, 3-Asynchronous step-down converter omwe amakonzedwa kuti apange mapangidwe ang'onoang'ono pogwiritsa ntchito bwino kwambiri komanso kuphatikiza ma MOSFET apamwamba komanso otsika.Kusungirako danga kwina kumatheka kudzera muulamuliro wamakono, womwe umachepetsa chiwerengero cha zigawo, ndi
kusankha mafupipafupi osinthasintha, kuchepetsa phazi la inductor.Njira yoyambira yotulutsa magetsi imayendetsedwa ndi pini ya SS / TR yomwe imalola kugwira ntchito ngati mphamvu yodziyimira yokha kapena potsata zochitika.Kutsatizana kwa mphamvu kumathekanso pokonzekera bwino zotsegulira ndi mapini otseguka amphamvu.Kuzungulira kwa kuzungulira kwaposachedwa kwapamtunda wa FET kumateteza chipangizocho pakachulukirachulukira ndipo kumakulitsidwa ndi malire apano omwe amalepheretsa kuthawa komwe kulipo.Chitetezo cha hiccup chimayambika ngati vuto la overcurrent likupitirirabe kwa nthawi yayitali kuposa nthawi yokonzedweratu.Kuzimitsa kwa kutentha kumayimitsa gawolo pamene kutentha kwa kutentha kupitirira kutentha kwa kutentha.TPS54320 ikupezeka mu pini 14, 3.5-mm × 3.5-mm VQFN, phukusi lowonjezera kutentha.Chidziwitso cha Chipangizo PART NUMBER PACKAGE BODY SIZE (NOM) TPS54320 VQFN (14) 3.50 mm × 3.50 mm, onani mapaketi onse omwe alipo. chowonjezera chokonzekera kumapeto kwa pepala la data.
