It seems like there's an infinite number of different devices that these backlight inverters use. If so, the only advice I can offer you is to try to find a used one in a computer repair shop, and if you use a different number, replace the pair. Next time I run into the problem of finding one, I'm going to try to use two discrete mosftets in place of the IC. John |

put finger to keyboard and composed: Im looking for this IC in a LCD television. Does anyone have one? Thanks "The BM2576 series are step-down switching regulators": http://www.086ic.cn/ic/BM2576.pdf There are two package styles, TO-220 and TO-263. There are also three versions of this chip - 3.3V, 5.0V, and ADJ(ustable). These are probably equivalent chips: http://www.onsemi.com/pub_link/Collateral/LM2576-D.PDF http://www.micrel.com/_PDF/lm2576.pdf http://www.national.com/ds/LM/LM2576.pdf#page=1 - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |
