Tsanangudzo yeTPS53219A
Iyo TPS53219A mudziyo idiki-saizi imwe bhagi controller ine adaptive ON-nguva D-CAPmode control.Chishandiso ichi chakakodzera yakaderera kubuda voltage, yakakwira ikozvino, PC system simba njanji uye yakafanana poindi-ye-mutoro (POL) magetsi emagetsi muzvigadzirwa zvevatengi vedhijitari.Iyo diki pasuru uye diki pini-kuverenga chengetedza nzvimbo paPCB, nepo yakatsaurirwa EN pini uye pre-yakasetwa frequency sarudzo inorerutsa dhizaini yemagetsi.Iyo skip modhi pamwenje mitoro mamiriro, yakasimba madhiraivha, uye yakaderera-parutivi FET RDS(pa)ikozvino sensing inotsigira kuderera-kurasikirwa uye kukwirira kwepamusoro, pamusoro pehupamhi hwekutakura huwandu.The conversion input voltage (high-side FET drain voltage) range iri pakati pe 4.5 V ne 25 V, uye inobuda voltage range iri pakati pe 0.6 V ne 5.5 V. TheTPS53219A inowanikwa mu 16-pini, QFN package inotsanangurwa kubva -40 ° C kusvika +85°C.
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.
