Iyo TPS54140A mudziyo ndeye 42-V, 1.5-A, nhanho-pasi regulator ine yakabatanidzwa yakakwirira-parutivi MOSFET.Yazvino-modhi yekudzora inopa nyore muripo wekunze uye inoshanduka yechikamu sarudzo.Iyo yakaderera ripple-pulse skip modhi inoderedza iyo isina-mutoro, yakadzorwa inobuda inopa ikozvino ku116 µA.Uchishandisa pini yekugonesa, kuvharika kwekugovera ikozvino kunoderedzwa kusvika 1.3 µA.
Undervoltage lockout inoiswa mukati me2.5 V, asi inogona kuwedzerwa uchishandisa pini yekugonesa.Iyo yekubuda voltage yekutanga rampu inodzorwa neinononoka yekutanga pini iyo inogona zvakare kugadzirwa kuti iite sequencing / yekutevera.Simba rekudhonza rakavhurika chiratidzo chakanaka chinoratidza kubuda kuri mukati me94% kusvika 107% yemagetsi ayo.
Iyo yakakura switching frequency renji inobvumira kunyatsoita uye yekunze chikamu saizi kuti igadziriswe.Frequency kupeta kumashure uye kuvharika kwemafuta kunodzivirira chikamu panguva yekuremerwa mamiriro.
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.
