假如您是公司 可以找這些公司來介紹
假如您是個人 恐怕還是mbi5026這種標準款的用一用比較快作者: SamT 時間: 2008-2-21 08:49 PM
LM3430 - Boost Controller for LED Backlighting
LM3432 - 6-Channel Current Regulator for LED Backlight Application
recommend part: MSL3162 with 16 strings and internal MOSFET,Max per string is 10 pcs LEDs.
mSilica ’s LCD TV family of LED drivers are highly integrated system-centric devices which use external DC-DC converters and external or internal MOSFETs integrated on the chip depending on the current requirements of the LEDs. These parts require minimal external components and are highly efficient. Our adaptive PowerSaver technology offers very accurate string current and string-to-string matching; fault detection; thermal protection; very wide dimming range for improved contrast; and sync capability with the video for reduced motion blur. The parts include user-programmable non-volatile memory for systems to initialize in a known state.
mSilica supports both of the main LED configurations for LCD TVs:作者: cliff2006 時間: 2008-10-25 02:54 AM 標題: 可用 16 Channel x3 我目前Run 的Case 用 240 個LED! 設計如下, 請參考!
每個Channel 4個LED串接, 採用 16Channel 的國產IC( 如 SITI 的 DM13A), 因此1個IC 可推 4*16 =64個 LED!
接下來:
(a). 用 3個 DM13A(成本不高) , 簡單明瞭. => 64 * 3 = 192 LED (MAX )
(b). 用 1/3 的 Duty Cycle 去推, => 64 * 3 = 192 LED (MAX )作者: jerryyao 時間: 2009-3-13 10:21 AM
HI hsienyi,
我有一顆IC可能符合你的需求,我可以寄規格輸給你,請回信告知你的email jerry@chipswork.com.tw
