Tsanangudzo yeTPS548B22
Iyo TPS548B22 mudziyo ndeye compact single buck converter ine adaptive pane-nguva, D-CAP3 modhi yekudzora.Yakagadzirirwa kurongeka kwepamusoro, kushanda kwepamusoro, mhinduro yekukurumidza, nyore-kwe-kushandisa, yakaderera yekunze chikamu chechikamu, uye nzvimbo-inoziva simba masisitimu.
Chishandiso ichi chine pfungwa yakazara yekusiyanisa, TI yakabatanidzwa FETs ine yakakwira-sideon-resistance ye4.1 mΩ uye yakaderera-padivi-inopokana ye1.9 mΩ.Mudziyo wacho unoratidzawo zvakarurama 0.5%, 0.9-V referensi ine ambient tembiricha iri pakati -40 ° C uye +125 ° C. Makwikwi emhando anosanganisira: yakaderera kwazvo yekunze chikamu chechikamu, kurongeka kwakaringana kwekuremerwa uye mutsara, kubuda kwevoltage setpoint accuracy, auto- skip kana FCCM modhi kushanda, uye mukati-soft-kutanga kutonga.
Iyo TPS548B22device inowanikwa mu7 mm × 5 mm, 40-pini, LQFN-CLIP (RVF) package (RoHs isingabhadharwi).
1. Ndivanaani vashandi mudhipatimendi rako reR & D?Ndezvipi zvidzidzo zvako?
-R & D Mutungamiriri: gadzira chirongwa chekambani chenguva refu R & D uye ubate gwara rekutsvaga nekusimudzira;Tungamira uye tarisa r&d dhipatimendi kuti iite kambani r&d zano uye yegore R&D chirongwa;Dzora kufambira mberi kwekugadzirwa kwechigadzirwa uye gadzirisa chirongwa;Gadzira yakanakisa chigadzirwa chekutsvagisa uye timu yekusimudzira, yekuongorora uye yekudzidziswa ine chekuita nehunyanzvi vashandi.
R & D Maneja: gadzira chigadzirwa chitsva R & D kuronga uye kuratidza kugona kwechirongwa;Tarisa uye gadzirisa kufambira mberi uye kunaka kwer&d basa;Tsvagurudza kugadzirwa kwechigadzirwa chitsva uye kurudzira mhinduro dzinoshanda zvinoenderana nezvinodiwa nevatengi munzvimbo dzakasiyana
Vashandi veR&d: unganidza uye gadzirisa data rakakosha;Computer programming;Kuita zviedzo, bvunzo uye ongororo;Gadzirira zvinhu uye zvishandiso zvekuyedza, bvunzo uye ongororo;Rekodha data yekuyera, ita kuverenga uye gadzira machati;Ita ongororo dzenhamba
2. Ndeipi yako chigadzirwa tsvakurudzo uye budiriro pfungwa?
-Kufunga kwechigadzirwa uye sarudzo yechigadzirwa pfungwa uye yekuongorora tsanangudzo yechigadzirwa uye dhizaini dhizaini uye kusimudzira chigadzirwa kuyedzwa uye kusimbiswa kwekutanga kumusika.
