Tsanangudzo yeTPS53319
Iyo TPS53318 uye TPS53319 midziyo ndeye D-CAP modhi, 8-A kana 14-A synchronous switchers ine yakabatanidzwa MOSFETs.Iwo akagadzirirwa nyore kushandisa, yakaderera yekunze chikamu kuverenga, uye nzvimbo-inoziva masimba masimba.
Midziyo iyi inoratidzira chaiyo 1%, 0.6-V referensi, uye yakasanganiswa inosimudzira switch.Sample yeanokwikwidza maficha anosanganisira: 1.5-V kusvika 22-V yakafara shanduko yekuisa voltage renji, yakaderera kwazvo yekunze chikamu kuverenga, D-CAP™ modhi yekudzora yekukurumidza kukurumidza kupfupi, auto-skip mode mashandiro, yemukati nyoro-kutanga kutonga, inosarudzwa. frequency, uye hapana chikonzero chemuripo.
Iyo yekushandura yekupinda voltage inotangira pa1.5 V kusvika 22 V, iyo yekugovera voltage renji kubva ku4.5 V kusvika 25 V, uye inobuda voltage renji kubva 0.6 V kusvika 5.5 V.
Midziyo iyi inowanikwa mu5 mm x 6 mm, 22-pini QFN package uye inotsanangurwa kubva -40°C kusvika 85°C.
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.
