Tsanangudzo yeLM22672
Iyo LM22672 switching regulator inopa ese mabasa anodiwa kuti aite inoshanda yakakwira voltage nhanho-pasi (buck) regulator uchishandisa mashoma ekunze zvinhu.Iyi iri nyore kushandisa regulator inosanganisira 42 V N-channel MOSFET switch inokwanisa kupa inosvika 1 A yekuremerwa ikozvino.Yakanakisa mutsara uye mutoro wekutonga pamwe nekushanda kwakanyanya (> 90%) inoratidzwa.Voltage modhi yekudzora inopa hupfupi hushoma pane-nguva, ichibvumira iyo yakakura chiyero pakati pekuisa uye kubuda voltages.Muripo wemukati weloop zvinoreva kuti mushandisi haana basa rinonetesa rekuverenga zvikamu zvemuripo we loop.Yakagadziriswa 5 V yakabuda uye inogadziriswa inobuda voltage sarudzo dziripo.
Iyo default switching frequency yakaiswa pa500 kHz ichibvumira zvidiki zvekunze zvikamu uye yakanaka yenguva pfupi mhinduro.Mukuwedzera, iyo frequency inogona kugadziriswa pamusoro pe200 kHz kusvika 1 MHz ine imwechete yekunze resistor.Iyo yemukati oscillator inogona kuwiriraniswa kune system wachi kana kune oscillator yemumwe mutongi.Iyo chaiyo inogonesa yekuisa inobvumira kurerutsa yekudzora kudzora uye sisitimu simba kutevedzana.Mukuvhara mode iyo regulator inodhonza chete 25 µA (typ).Iyo inogadziriswa yakapfava-yekutanga chimiro inopiwa kuburikidza nekusarudzwa kweimwe yekunze capacitor.Iyo LM22672 zvakare yakavaka mukuvharika kwekupisa, uye ikozvino kudzikamisa kudzivirira kubva netsaona yakawandisa.
Iyo LM22672 inhengo yeTexas Instruments' SIMPLE SWITCHER® mhuri.Iyo SIMPLE SWITCHER® pfungwa inopa nyore kushandisa dhizaini yakakwana uchishandisa huwandu hushoma hwezvikamu zvekunze uye TI WEBENCH® dhizaini yekushandisa.TI's WEBENCH® chishandiso chinosanganisira maficha akadai seyekunze chikamu kuverenga, magetsi simulation, thermal simulation, uye Build-It mabhodhi kuitira nyore dhizaini-mukati.
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.
