I-BD18336NUF-M yi-3 x 3 x 1mm yomqhubi wangoku we-IC onokuthi ahambise i-400mA ngokuqhubekayo (i-600mA kwi-50% yomjikelo womsebenzi) kumtya wee-LED ezimhlophe ezintathu okanye imitya efanayo yee-LED.
"Ubushushu obuveliswe zii-LED bucinezelwe ngumsebenzi ohlangeneyo wokuhla komgangatho," ngokweRohm. "Iziphumo ezilungelelanisiweyo ze-thermal zilinganisela ubushushu obuveliswa zii-LEDs, zikhulisa ixesha labo lokuphila, nto leyo eyenza ukuba umqhubi we-LED alungele ezimhlophe kunye nee-LED ezibomvu nezimthubi."
Kanye nokuhla kwe-thermal ukukonyusa ukuthembeka, ukhuselo lubandakanya ukubonwa okuvulekileyo kwe-LED, ukukhutshwa kokukhuselwa okufutshane kwesekethe, i-SET pin ukhuselo lwesekethe olufutshane (jonga umzobo), isilumko esingaphezulu kwamandla ombane, ukugqitha okwangoku kumandla ombane ancitshisiweyo, ukuphuma kweflegi. Ayilulo lonke ukhuseleko olusebenza ngemitya ehambelana nee-LED.
Isiphumo sangoku sinokumelana nenkqubo, kwaye kukho eyakhelweyo kwi-PWM oscillator esebenza ne-RC yangaphandle yokulungisa ifomathi yamaza, okanye uphawu lwangaphandle lwePWM lunokusetyenziswa.
Ukusetyenziswa: i-387mA ukuya kwii-LED ezimhlophe ezintathu, umjikelo womsebenzi we-10% (300Hz)
Ukusebenza kungaphaya kwe -40 ukuya kwi-150 ° C, kwaye kukho unxibelelwano lwangaphandle lwe-thermistor.
Ukusebenza kukwayi-5.5 ukuya kuma-20V (ukusinda ukuya kwi-42v), nangona ii-LEDs zifuna ukujikeleza i-9V ukuze zisebenze ngokufanelekileyo.
Ukupakisha i-VSON10FV3030, kwaye i-chip ilungele i-AEC-Q100 yeBakala 1.
Izicelo zilindelwe kwizibane zohlobo lwe-socket ze-automotive ezifana nezibane zangemva, izikhombisi zokujika, izibane zenkungu, izibane zokuma okanye izibane ezisebenza emini.
"I-ROHM yamkela imeko yentengiso eya kwi-miniaturization kunye nomqhubi wayo we-LED omtsha ngaphandle kokuyekisa kwiimpawu zokhuseleko kunye nokusebenza, utshilo umphathi wentengiso weRohm uStefan Drouzas.
