Looking for BM2576 (Semiconductor)

Sounds like one of those small 8 pin smd backlight inverter drivers. (?) 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.

"The BM2576 series are step-down switching regulators":

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:
