Iyo TPS54320 izere-inoratidzwa 17-V, 3-Asynchronous nhanho-pasi inoshandura iyo inogadziridzwa diki dhizaini kuburikidza nehunyanzvi hwepamusoro uye yakasanganiswa yepamusoro-parutivi uye yakaderera-parutivi MOSFETs.Imwezve nzvimbo yekuchengetedza inowanikwa kuburikidza neazvino mode control, iyo inoderedza chikamu chechikamu, uye ne
kusarudza high switching frequency, kuderedza footprint ye inductor.Kubuda kwevoltage kutanga-up ramp inodzorwa ne SS / TR pini iyo inobvumira kushanda seimwe yemagetsi ega ega kana mumamiriro ekutevera.Kutevedzana kwesimba kunogonekawo nekugadzirisa nemazvo inogonesa uye yakavhurika yekudhonza simba mapini akanaka.Kutenderera nekutenderera kwazvino kudzikisira pane yakakwira-parutivi FET inodzivirira chishandiso mumamiriro ekuremedza uye inosimudzirwa neyakadzikira-padivi kutsvagisa muganhu wazvino unodzivirira kutiza kwazvino.Kudzivirirwa kweHiccup kunokonzereswa kana iyo overcurrent mamiriro akaenderera kwenguva yakareba kupfuura preset nguva.Thermal shutdown inodzima chikamu kana tembiricha yekufa ichipfuura tembiricha yekudzima.Iyo TPS54320 inowanikwa mu 14-pini, 3.5-mm × 3.5-mm VQFN, thermally enhanced package.Device Information PART NUMBER PACKAGE BODY SIZE (NOM) TPS54320 VQFN (14) 3.50 mm × 3.50 mm, ona mapasuru ese aripo inorongeka yekuwedzera pamagumo epepa re data.
