Tsanangudzo yeTPS54336A
Mhuri yeTPS5433xA yezvishandiso ndeye synchronous converters ne-input-voltage range ye 4.5 kusvika ku28 V. Izvi zvinosanganisira yakabatanidzwa yakaderera-side switching FET inobvisa kudiwa kwekunze diode iyo inoderedza chikamu chechikamu.
Kubudirira kunowedzera kuburikidza neiyo yakabatanidzwa 128-mΩ uye 84-mΩ MOSFETs, yakaderera IQ uye pulse kusvetuka pamutoro wakareruka.Uchishandisa pini yekugonesa, iyo yekuvharisa yekugovera ikozvino yakaderedzwa kusvika 2 μA.Iyi nhanho-pasi (buck) inoshandura inopa chaiyo mutemo kune akasiyana mitoro ine yakanyatso kudzorwa voltage referensi iri 1.5% pamusoro petembiricha.
Cycle-by-cycle yazvino kudzikamisa padivi-parutivi MOSFET inodzivirira iyo TPS5433xA mhuri yemidziyo mumamiriro ekuremedza uye inosimudzirwa neakaderera-parutivi kutsvagisa muganhu wazvino unodzivirira kutiza kwazvino.Iyo yakaderera-padivi kunyura ikozvino-muganho unodzima yakaderera-parutivi MOSFET kudzivirira yakawandisa reverse ikozvino.Kudzivirirwa kweHiccup kunokonzereswa kana iyo overcurrent mamiriro akaenderera mberi kwenguva yakareba kupfuura preset nguva.Thermal shutdown inodzima mudziyo kana tembiricha yekufa ichidarika chikumbaridzo uye inogonesa mudziyo zvakare mushure meiyo yakavakirwa-mukati yekupisa hiccup nguva.
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.
