Power Supply IC Series for TFT-LCD Panels
12V Input Multi-channel System Power Supply IC
BD8160AEFV
No.09035EBT01
●Description The BD8160AEFV 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 2.6 A N-channel FET. 3) Incorporates positive/negative charge pumps. 4) Input voltage limit: 8 V to 18 V 5) Feedback voltage: 1.162 V ± 1% 6) Switching frequency: 500 kHz / 750kHz 7) Protection circuit: Under voltage lockout protection circuit Thermal shutdown circuit Overcurrent protection circuit Short Circuit Protection Overvoltage protection circuit for VS voltage (Boost DC/DC output) 8) HTSSOP-B28 Package
●Applications Power supply for the TFT-LCD panels used for LCD TVs
●Absolute maximum ratings (Ta = 25°C)
