Tsanangudzo yeTPS62147
Iwo TPS62147 uye TPS62148 ane hunyanzvi hwepamusoro uye ari nyore kushandisa nhanho-pasi DC/DC converter, zvichibva paDCS-Control™Topology.Iyo yakafara yekupinza voltage renji ye3-V kusvika 17-V inoita kuti ive yakakodzera kune akawanda-sero Li-Ion pamwe ne12-V yepakati yekugovera njanji.Zvishandiso zvinopa 2-A inoenderera yakabuda ikozvino.Vanoisa otomatiki Masimba Save Mode pamitoro yakareruka kuti uchengetedze kushanda kwepamusoro mukati memutoro wese.Nezvo, ivo vakanyatsokodzera maapplication ayo anoda yakabatana standbyperformance, senge maindasitiri PC uye vhidhiyo yekutarisa.Iine iyo MODE pini yakadzikira, iyo switchingfrequency inogadziridzwa otomatiki zvichibva pane inobuda ikozvino uye zvakare pakuisa uye kubuda kwevoltage.Iyi tekinoroji inodaidzwa kunzi Automatic Efficiency Enhancement (AEE™) uye inochengetedza highconversion kunyatsoshanda pamusoro pesero rekushanda.TPS62147, TPS62148 inopa 1% kubuda kwevoltage kurongeka muPWM modhi uye nekudaro inogonesa dhizaini yemagetsi ane yakakwira kubuda kwevoltage kunyatsoita.Iyo pini yeFSEL inobvumira kuseta frequency yekuchinja mukumanikidzwa PWM modhi ye1.25 MHz kana 2.5 MHz, zvichiteerana.
Ikozvino kunyarara ndeye 18 µA.Mukuvhara mode ikozvino inowanzoita 1µA.
Iwo maturusi anowanikwa seyakagadziriswa vhezheni, akaiswa mu3-mm × 2-mm VQFNpackage.
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.
