... BD8166EFV ●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. ● ...

... DLS (9) Negative-side Charge Pump Settings BD8166EFV incorporates a charge pump controller for negative voltage, thus making it possible to generate stable gate voltage. The output voltage is determined by the following equation. As the setting range, 10 kΩ to 330 kΩ is recommended. If the resistor is set lower than 10 kΩ, it causes reduction of power efficiency set more than 330kΩ, the offset voltage becomes larger by the input bias current of 0.4 µ ...
