I-BD18336NUF-M iyi-3 x 3 x 1mm engashayeli wamanje IC engakwazi ukuletha i-400mA ngokuqhubekayo (600mA kumjikelezo womsebenzi ongu-50%) ngentambo yama-LED amathathu amhlophe noma izintambo ezifanayo zama-LED.
"Ukushisa okwenziwe ama-LED kucindezelwa umsebenzi odidiyelwe wamanje wokwehlisa izinga," kusho uRohm. "Okwamanje okukhiphayo okushisayo kukhawulela ukushisa okwenziwe ama-LED, kukhulisa isikhathi sabo sokuphila, okwenza umshayeli we-LED alungele amhlophe kanye nama-LED abomvu naphuzi."
Kanye nokushiswa kwe-thermal ukukhulisa ukuthembeka, ukuvikelwa kufaka phakathi ukutholwa okuvulekile kwe-LED, ukuvikelwa kokuvikelwa kwesifunda okufushane, ukuvikelwa kwesekethe okufushane kwe-SET (bona idayagramu), isimungulu esinamandla amaningi, ukudlula kwamanje kumandla wehlisiwe, ukukhishwa kwefulegi lephutha. Akukhona konke ukuvikelwa okusebenza ngezintambo ezifanayo zama-LED.
Okokukhipha kwamanje kuyaphikisana nokuhlelwa, futhi kune-oscillator eyakhelwe ngaphakathi ye-PWM esebenza ne-RC yangaphandle ukulungisa ifomathi yamaza, noma kungasetshenziswa isiginali ye-PWM yangaphandle.
Isicelo: 387mA kuya kuma-LED amathathu amhlophe, umjikelezo womsebenzi ongu-10% (300Hz)
Ukusebenza kungaphesheya -40 kuye + 150 ° C, futhi kukhona ukuxhumana kwangaphandle kwe-thermistor.
I-Operation ibuye ibe ngaphezu kwe-5.5 - 20V (ukusinda iye ku-42v), yize ama-LED adinga cishe i-9V ukuze isebenze kahle.
Ukupakisha yi-VSON10FV3030, futhi i-chip ifanelekela i-AEC-Q100 Ibanga 1.
Izicelo kulindeleke ukuthi zibe ngamalambu e-LED asezimoto afana nezamalambu angemuva, izinkomba zokujika, amalambu enkungu, amalambu okuma noma amalambu asebenza emini.
"I-ROHM yamukela ukuthambekela kwemakethe okubhekisele ekusetshenzisweni kwezinto ezincane ngomshayeli wayo omusha we-LED ngaphandle kokuyekethisa kwezokuphepha nokusebenza," kusho umphathi wezokukhangisa wakwaRohm uStefan Drouzas.
