Tsanangudzo yeTPS61252
Chishandiso cheTPS61252 chinopa mhinduro yemagetsi kune zvigadzirwa zvinofambiswa neatatu-sero alkaline, NiCd kana NiMH bhatiri, kana bhatiri-sero Li-Ion kana Li-polymer bhatiri.Iyo yakafara yekuisa voltage renji yakanakira kugonesa inotakurika application senge mbozhanhare kana komputa peripherals.Chigadzirwa chacho chine resistor programmable (RILIM) yekuisa muganho wazvino uye inokodzera zvakasiyana siyana zvekushandisa.
Munguva yekuremerwa kwakareruka, mudziyo unopinda otomatiki skip modhi (PFM), iyo inobvumira iyo inoshandura kuchengetedza inodiwa inobuda voltage, ichingodhirowa 30 µA quiescent ikozvino kubva mubhatiri.Izvi zvinobvumira kugona kwakanyanya pamhepo yakadzikama yakanyarara.
TPS61252 inobvumira kushandiswa kwediki inductors uye capacitor kuwana diki mhinduro saizi.Iko mukana wekudzikisa muganho wazvino neanopikisa wekunze unopa mukana wekushandisa kwemuviri kunyange madiki inductors ane yakaderera yakayerwa macurrents kuti uwedzere kudzikisa huwandu hwemhinduro saizi yemagetsi.Panguva yekuvhara, mutoro unobviswa zvachose kubva kubhatiri.Iyo TPS61252 inowanikwa mune 8-pini WSON package inoyera 2 mm × 2 mm (DSG).
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.
