Tsanangudzo yeTPS92513HV
Iyo TPS92513/HV ndeye 1.5A nhanho-pasi (buck) ikozvino maregulator ane yakabatanidzwa MOSFET kutyaira yakakwira maLED azvino.Inowanikwa ne42 V uye 60 V (HV) ekuisa marengesheni, aya madhiraivha eLED anoshanda pamushandisi akasarudzwa akamisikidzwa-frequency ane peak-current mode control uye anoendesa yakanakisa mutsara uye mutoro wekutonga.
Iwo TPS92513/HV madhiraivha e LED anoratidza akapatsanurwa eanalog uye pulse wide modulation (PWM) inodzima pasina kukanganisa kupenya kutonga kuwana mutsauko weyeshiyo yehukuru kupfuura 10: 1 uye yakakura kupfuura 100: 1, zvichiteerana.Iyo PWM yekupinda inofambirana neyakaderera-voltage logic miyero kuitira nyore interface kune yakakura siyana ye microcontrollers.Iyo analog LED ikozvino setpoint inogadziriswa kubva 0 V kusvika 300 mV uchishandisa iyo IADJ yekuisa ine yekunze 0 V kusvika 1.8 V chiratidzo.
Kune akawanda-tambo maapplication uchishandisa maviri kana anopfuura eTPS92513/HV madhiraivha e LED, iyo yemukati oscillator inogona kufambiswa newachi yekunze ichiona kuti ma converter ese anoshanda pane akajairika frequency nekudaro achidzikisa mukana wekurova frequency uye kurerutsa system EMI kusefa.Iyo inogadziriswa yekupinda pasi-voltage kukiya (UVLO) ine hysteresis inopa kuchinjika mukuseta kutanga/kumisa mavheti zvichienderana nemamiriro ekupa voltage.
Iyo TPS92513 inosanganisira kutenderera-ne-kutenderera kuchengetedzwa kwepamusoro-soro uye yekudzivirira yekuvhara kwemafuta.Inowanikwa mune gumi-pini HVSSOP PowerPAD™ package.
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.
