♠ TPS92638-Q1 8-Channel Linear LED Keaukaha Me PWM Dimming
ʻO ka TPS92638-Q1 kahi mea hoʻokele LED laina ʻewalu-kanal me ka mana dimming PWM. He kūpono kona hoʻolālā no ka hoʻokele ʻana i nā kaula he nui o nā LED a hiki i kahi ʻano
mana mana.
Hiki i kēia hāmeʻa ke hoʻokele i nā kaula ʻewalu me hoʻokahi a ʻekolu mau LED i kēlā me kēia kaula, ma ka huina o kēia manawa a hiki i ka 70 mA i kēlā me kēia kahawai. Hiki ke hoʻohālikelike ʻia nā mea hoʻopuka e hāʻawi i ke kaʻa kiʻekiʻe a hiki i 560 mA.
Ma nā noi laina he nui, hāʻawi ka hāmeʻa i ka pono o ka loaʻa ʻana o ka pilina cathode maʻamau o nā stings LED. No laila, hoʻokahi wale nō uea hoʻihoʻi e pono ai ma mua o hoʻokahi no ke kaula LED e pono ai kahi ʻōnaehana me ka ʻaoʻao haʻahaʻa o kēia manawa.
Loaʻa i ka hāmeʻa ka hiki ke hoʻololi i kēia manawa LED ma waena o ka manawa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa no nā noi hoʻomaha a me ka huelo. Hoʻonohonoho ʻelua mau mea pale kuhikuhi i nā pae ʻelua LED i kēia manawa mai kēlā me kēia puka.
ʻO ka mea nānā wela i hoʻokomo ʻia e hōʻemi i ka LED drive i kēia manawa inā ʻoi aku ka mahana o ka junction IC i kahi paepae wela. Hiki ke hoʻolālā ʻia ka paepae wela ma o ka pale pale waho. Hiki i kekahi ke hoʻopau i ka hiʻohiʻona thermal current-monitor ma ka hoʻopili ʻana i ka pine TEMP i ka lepo. Loaʻa ka puka o ka wela hui e like me ka volta analog ma ke ʻano he koho papahana hale hana.
