BD8160EFV

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) Parameter Symbol Rating Supply Voltage SUP,VIN 20 Power Dissipation Pd 4700* Operating Temperature Range Topr -40～+85 Storage Temperature Range Tstg -55～+150 Junction Temperature Tjmax 150 SW Voltage VSW 21 SWB Voltage VSWB 19 EN1,EN2 Voltage VEN1,VEN2 19 * Derating in done 37.6mW/℃ for operating above Ta≧25℃(On 4-layer 70.0mm×70.0mm×1.6mm board) ●Recommendable Opera...
