BD8166EFV 12V Input Multi-channel System Power Supply

The BD8166EFV is a system power supply for the TFT-LCD panels used for liquid crystal TVs. Incorporates two high-power FETs with low on resistance for large currents that emplo y high-power packages, thus drivin g large current loads while suppressing the generation of heat. A charge pump controller.
