摘要： For a charge pump, a control circuit switches two or more input voltages to apply to one or more pumping capacitors under auto-sensing control to modulate a maximum pumping voltage as close as to a demanded output voltage to thereby reduce the difference between the maximum pumping voltage and the output voltage for efficiency and thermal improvement of the charge pump. The maximum pumping voltage is produced by mixing the different input voltages and the charge pump may provide more operation modes.

摘要： In a method for a DC-DC power conversion performed by a switching mode buck voltage converter, the power conversion is split into two or more stages, and a feed-forward signal is generated by one of the stages and sent to another stage prior thereto. The feed-forward signal is generated by responding to a load current transient, such as output voltage drop, ON-duty increment or decrement occurred in the PWM control loop, error amp output swinging, and any other detectable signals in response to load current transient of the voltage converter. As a result, the performance of the DC-DC voltage converter is improved due to the prior stage modulated early in time, and both lower ripple current and peak current in steady state operations and fast response to load current transient conditions could be simultaneously obtained.
