Power Supply IC Series for TFT-LCD Panels 12V Input Multi-channel System Power Supply IC BD8166EFV No.09035EBT14 ●Description 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 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. ●Features 1) Step-up and step-down DC/DC converter 2) Incorporates 2-A N-channel FET. 3) Incorporates positive/negative charge pumps. 4) Incorporates a gate shading function. 5) Input voltage limit: 6 V to 18 V 6) Feedback voltage: 1.25 V ± 1.6% 7) Switching frequency: 500 kHz 8) Pr [ ... ]
