BD8166EFV

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 emplo y high-power packages, thus drivin g 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) Protection circuit: Undervoltage lockout protection circuit Thermal shutdown circuit Overcurrent protection circuit Short protection circuit of timer latch type 9) HTSSOP-B40 Package ●Applications Power supply for the TFT-LCD panels used for LCD TVs ●Absolute maximum ratings (Ta = 25℃) Parameter S ymbol Limit Power supply voltage Vcc, PVCC 19 Vo1 voltage Vo1 19 Vo2 voltage Vo2 40 IG Voltage IGH 7 Maximum junction temperature Tjmax 150 Power dissipation Pd 4700*1 mW Operating temperature range Topr -40 to 85 Storage temperature range Tstg -55 to 150 * Reduced by 37.6 mW/℃ ov er 25℃, when mounted on a glass epoxy 4-layer board (70 mm  70 mm  1.6 mm) (Copper foil on back 70...
