Tsanangudzo yeTPS630250
Iwo TPS63025x ane hunyanzvi hwepamusoro, akadzikama akadzikama ikozvino buck-boost maconverter akakodzera kushandiswa uko magetsi ekuisa akakwira kana kudzika pane yakabuda.Mapoinzi ekubuda anogona kuenda akakwira se2 A muboost mode uye akakwira se4 A mune buck mode.Iyo yakawanda yeavhareji yemazuva ano mumaswichi inogumira kune yakajairwa kukosha kwe4 A. Iyo TPS63025x inodzora kubuda kwevoltage pamusoro peiyo yakazara yekuisa voltage renji nekuchinja otomatiki pakati pebuck kana boost modhi zvichienderana neiyo yekuisa voltage inovimbisa shanduko isina musono pakati pemodhi.Iyo buck-boost inoshandura yakavakirwa pane yakatarwa frequency, pulse-width-modulation (PWM) controller ichishandisa synchronous rectification kuti iwane yakanyanya kunaka.Pamhepo yakaderera mitoro, inoshandura inopinda Power Save Mode kuti ichengetedze hunyanzvi hwepamusoro pamusoro peiyo yakazara mutoro wazvino renji.Iko kune PFM/PWM pini inobvumira mushandisi kusarudza pakati peotomatiki PFM/PWM modhi oparesheni uye yekumanikidza PWM kushanda.Munguva yePWM modhi yakagadziriswa-frequency yeanowanzo 2.5 MHz inoshandiswa.Iyo inobuda voltage inogadziriswa uchishandisa yekunze resistor divider, kana inogadziriswa mukati mukati chip.Iyo inoshandura inogona kuvharwa kuti ideredze kupera kwebhatiri.Panguva yekuvhara, mutoro unobviswa kubva mubhatiri.Chishandiso ichi chakaiswa mupakeji ye20-pini yeWCSP inoyera 1.766 mm × 2.086mm uye 14-pini HotRod pasuru inoyera 2.5 mm × 3mm.
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.
