BD18336NUF-M ndi 3 x 3 x 1mm driver driver IC yomwe imatha kupulumutsa 400mA mosalekeza (600mA pa 50% yoyendetsa ntchito) mu chingwe cha ma LED atatu oyera kapena zingwe zofanana za ma LED.
"Kutentha komwe kumapangidwa ndi ma LED kumayimitsidwa ndi ntchito yophatikizira pakadali pano," malinga ndi Rohm. "Kutentha kosinthika kwamakono kumachepetsa kutentha komwe kumapangidwa ndi ma LED, kumawonjezera nthawi yawo yamoyo, zomwe zimapangitsa kuti driver woyendetsa akhale woyenera kuyera komanso ma LED ofiira ndi achikasu."
Komanso kutsitsa kwa matenthedwe kukulitsa kudalirika, zotchinjiriza zimaphatikizapo kuzindikira kotseguka kwa LED, kutulutsa chitetezo chachifupi, SET pini chitetezo chachifupi (onani chithunzi), osalankhula mopitilira muyeso, kulambalala kwamakono pamagetsi ochepetsedwa, kutulutsa kwa mbendera yolakwika. Sikuti chitetezo chonse chimagwira ndi zingwe zofanana za ma LED.
Zomwe zilipo pakadali pano ndizosavomerezeka, ndipo pali PWM oscillator yomanga yomwe imagwira ntchito ndi RC yakunja kuti isinthe mawonekedwe amawu, kapena siginecha ya PWM yakunja.
Ntchito: 387mA mpaka ma LED atatu oyera, 10% yoyendetsa ntchito (300Hz)
Ntchito idutsa -40 mpaka + 150 ° C, ndipo pali kulumikizana kwakunja kwa thermistor.
Ntchito imagwiranso 5.5 - 20V (kupulumuka mpaka 42v), ngakhale ma LED amafunikira mozungulira 9V kuti igwire bwino ntchito.
Kupaka ndi VSON10FV3030, ndipo chip ndi choyenera ku AEC-Q100 Gawo 1.
Mapulogalamu akuyembekezeredwa pamayendedwe amtundu wamagalimoto amtundu wamagalimoto monga nyali zakumbuyo, zowunikira, nyali za fog, nyali zamalo kapena nyali zoyendetsa masana.
"ROHM ikugwirizana ndi zomwe zikuchitika pamsika wama miniaturization ndi driver wake watsopano kwambiri wa LED osanyalanyaza chitetezo ndi magwiridwe antchito," atero oyang'anira otsatsa a Rohm Stefan Drouzas.
