♠ 40VIN, 75VOUT mau alakaʻi alakaʻi
ʻO ka LT®3755, LT3755-1 a me LT3755-2 nā mea hoʻokele DC/DC i hoʻolālā ʻia e hana ma ke ʻano he kumu mau no ka hoʻokele ʻana i nā LED kiʻekiʻe. Hoʻokele lākou i kahi ʻaoʻao haʻahaʻa waho N-channel mana MOSFET mai kahi lako 7.15V hoʻoponopono kūloko. ʻO ke alapine paʻa, ka hoʻolālā ʻano o kēia manawa ka hopena i ka hana paʻa ma luna o kahi ākea o ka lako a me nā voltage puka. ʻO kahi pine FB i kuhikuhi ʻia i ka ʻāina e lilo i mea hoʻokomo no kekahi mau hiʻohiʻona pale LED,a hiki no hoi i ka mea hoololi ke hana ma ke ano he kumu voli mau. ʻO kahi pine hoʻololi pinepine e hiki ai i ka mea hoʻohana ke hoʻolālā i ke alapine mai 100kHz a i 1MHz e hoʻonui i ka pono, hana a i ʻole ka nui o nā mea waho.
ʻO ka LT3755/LT3755-1/LT3755-2 manaʻo i kēia manawa ma ka ʻaoʻao kiʻekiʻe o ke kaula LED. ʻO ka ʻike ʻaoʻao kiʻekiʻe o kēia manawa ka hoʻolālā maʻalahi loa no ka hoʻokele LED, e ʻae ai i ka hoʻoikaika ʻana, ka mode buck a i ʻole ka hoʻonohonoho mode buck-boost. Hāʻawi ka hoʻokomo PWM i nā lakio dimming LED a hiki i ka 3000: 1, a ʻo ka hoʻokomo CTRL e hāʻawi i ka mana dimming analog hou.
