The BV6802 is a highly integrated power solution for AMOLED Display application, which uses a single-inductor-bipolar-output (SIBO) converter and three linear low-dropout regulators (LDO) to generate two positive and one negative voltage outputs. It does not need an extra charge pump circuit to generate the negative voltage output so that external capacitors required by the charge pump circuit can be eliminated and the smallest PCB footprint can be achieved.

The output voltages can be adjusted by SWIRE pin. Compared with the scheme of generating negative voltage by a charge pump circuit, the best energy conversion efficiency can only be obtained near the negative voltage ratio provided by its charge pump circuit. This SIBO architecture can provide a stable high conversion efficiency throughout the entire negative voltage adjusting range. Therefore, this solution can provide the optimal negative voltage output value according to different brightness requirements to reduce the power consumption of the AMOLED display significantly. This is the best solution that can optimize the solution form factor as well as display power consumption.
