Zvimiro zve LP8867-Q1
- AEC-Q100 Inokodzera kunyorera mota:
- Tembiricha yemudziyo giredhi 1:
- -40°C kusvika +125°C, TA
- Functional safety inokwanisa
- Zvinyorwa zviripo kubatsira kushanda kwekuchengetedza system dhizaini
- 3-, 4-Channel 120-mA inonyura ikozvino
- High dimming ratio ye10 000:1 pa100 Hz
- Yazvino yakaenzana 1% (yakajairika)
- LED String ikozvino inosvika 120 mA pachiteshi
- Zvinobuda zvinogona kusanganiswa kunze kwepamusoro ikozvino patambo
- Yakabatanidzwa inowedzera uye SEPIC inoshandura ye LED tambo simba
- Input voltage inoshanda renji 4.5 V kusvika 40 V
- Output voltage kusvika ku45 V
- Yakabatanidzwa 3.3-A Switch FET
- Kuchinja frequency 300 kHz kusvika 2.2 MHz
- Kuchinja mapindiro ekubatanidza
- Kuparadzira spectrum kune yakaderera EMI
- Kuona mhosva nekudzivirira
- Kutadza kubuda
- Input voltage OVP, UVLO uye OCP
- Boost block SW OVP uye inobuda OVP
- LED yakavhurika uye pfupi kukanganisa kukanganisa
- Simba-Mutsetse FET kutonga kwebhatiri bhazi kuchengetedza
- Otomatiki LED ikozvino kuderedzwa nekunze tembiricha sensor
- Thermal shutdown
Tsanangudzo yeLP8867-Q1
Iyo LP8867-Q1, LP8869-Q1 imotokari yakabatanidzwa zvakanyanya, yakaderera-EMI, iri nyore kushandisa LED mutyairi ane DC-DC inoshandura.Iyo DC-DC inoshandura inotsigira zvese kuwedzera uye SEPIC modhi maitiro.Chigadzirwa chacho chine mana kana matatu epamusoro-chaizvo-chaizvo masingi azvino anogona kubatanidzwa kune yakakwirira ikozvino kugona.
Iyo DC-DC inoshandura ine adaptive inobuda voltage control yakavakirwa pa LED kumberi voltages.Ichi chimiro chinoderedza kushandiswa kwesimba nekugadzirisa voltage kusvika kune yakaderera yakakwana pamwero mumamiriro ese.Yekudzikisa EMI DC-DC inotsigira kupararira kwekuchinja frequency uye yekunze kuwiriranisa nepini yakatsaurirwa.Iyo yakakura-renji inogadziriswa frequency inobvumira iyo LP886x-Q1 kudzivirira kukanganisa kune inonzwisisika frequency bhendi.
Iyo yekupinza voltage renji yeLP886x-Q1 inobva pa4.5 V kusvika 40 V kutsigira mota yekutanga-kumira uye mutoro wekurasa mamiriro.Iyo LP886x-Q1 inosanganisa yakakura yekuona kukanganisa maitiro.
