Zithunzi za TPS92513HV
The TPS92513/HV ndi 1.5A potsika pansi (buck) owongolera omwe ali ndi MOSFET yophatikizika yoyendetsa ma LED apamwamba.Zopezeka ndi 42 V ndi 60 V (HV) zolowetsamo, madalaivala a LEDwa amagwira ntchito pama frequency osankhidwa omwe amasankhidwa ndi peak-current mode control ndikupereka mizere yabwino kwambiri ndi katundu.
Madalaivala a TPS92513/HV LED amakhala ndi zolowetsa zosiyana za analogi ndi pulse wide modulation (PWM) dimming popanda kunyengerera kuwongolera kowala kukwaniritsa kusiyanitsa kwakukulu kuposa 10: 1 ndi wamkulu kuposa 100: 1, motsatana.Kulowetsa kwa PWM kumagwirizana ndi miyezo yotsika yamagetsi yamagetsi kuti ikhale yosavuta kumagulu osiyanasiyana a microcontrollers.Ma analogi amakono a LED amatha kusintha kuchokera ku 0 V mpaka 300 mV pogwiritsa ntchito kulowetsa kwa IADJ ndi chizindikiro chakunja cha 0 V mpaka 1.8 V.
Pazogwiritsa ntchito zingwe zambiri pogwiritsa ntchito ma driver awiri kapena kupitilira apo a TPS92513/HV LED, oscillator yamkati imatha kuyendetsedwa mopitilira muyeso ndi wotchi yakunja kuwonetsetsa kuti otembenuza onse amagwira ntchito pafupipafupi potero amachepetsa kuthekera kwa kugunda kwanthawi yayitali komanso kufewetsa kusefa kwa EMI.Kuyika kosinthika kwapansi pa-voltage lockout (UVLO) yokhala ndi hysteresis kumapereka kusinthika pakukhazikitsa ma voltages oyambira/kuyimitsa kutengera momwe ma voltage amaperekera.
TPS92513 imaphatikizapo chitetezo chozungulira-ndi-zungulira komanso chitetezo chotseka chamoto.Imapezeka mu phukusi la 10-pini la HVSSOP PowerPAD™.
1. Kodi ogwira ntchito m'dipatimenti yanu ya R & D ndi ndani?Kodi ziyeneretso zanu ndi zotani?
-R & D Mtsogoleri: pangani dongosolo la nthawi yayitali la R & D ndikumvetsetsa momwe kafukufuku ndi chitukuko;Kuwongolera ndi kuyang'anira dipatimenti ya r&d kuti ikwaniritse njira zamakampani ndi mapulani apachaka a R&D;Kuwongolera kupita patsogolo kwa chitukuko cha mankhwala ndikusintha dongosolo;Khazikitsani gulu labwino kwambiri la kafukufuku wazinthu ndi chitukuko, kufufuza ndi kuphunzitsa ogwira ntchito zaukadaulo.
Woyang'anira R & D: pangani mankhwala atsopano a R & D ndikuwonetsa kuthekera kwa dongosolo;Kuyang'anira ndi kuyang'anira momwe ntchito ya R&d ikuyendera;Fufuzani zachitukuko chazinthu zatsopano ndikupereka mayankho ogwira mtima malinga ndi zomwe makasitomala amafuna m'magawo osiyanasiyana
Ogwira ntchito ndi R&d: sonkhanitsani ndikusankha zofunikira;Mapulogalamu apakompyuta;Kuyesa, kuyesa ndi kusanthula;Konzani zida ndi zida zoyeserera, zoyeserera ndi kusanthula;Lembani deta yoyezera, pangani mawerengedwe ndikukonzekera ma chart;Chitani kafukufuku wamawerengero
2. Kodi lingaliro lanu la kafukufuku ndi chitukuko ndi chiyani?
- Lingaliro lazinthu ndi kusankha kwazinthu ndikuwunika tanthauzo lazinthu ndi kapangidwe ka pulani ya projekiti ndi kuyezetsa kwachitukuko ndikutsimikizira kukhazikitsidwa kwa msika
