ABSTRACT:
At the driving initiation, whether the output channels are enabled or disabled is determined by judging whether the voltages of the output channels are changed by a charging or discharging operation. The current output sources corresponding to the disabled output channels are turned off for power-saving. In the voltage conversion, the status of the disabled output channels is ignored, for accurately control of the voltage conversion.
