Product Summary
The BD8166EFV is a 12V input multi-channel system power supply IC. Incorporates two high-power FETs with low on resistance for large currents that employ high-power packages, thus driving large current loads while suppressing the generation of heat. A charge pump controller is incorporated as well, thus greatly reducing the number of application components. The applications of the BD8166EFV include Power supply for the TFT-LCD panels used for LCD TVs.
