Abstract
The disclosure provides for a slope voltage compensation circuit with an adaptive slope compensation method, in a DC-DC switching converter operating in current control mode, at duty cycles greater than 50%. The proposed solution allows for the dynamic range of useful operation to be extended, lowering the slope voltage compensation at the beginning of the cycle, and then increasing the compensation as 50% duty cycle is achieved. This method is based on voltage control instead of time, and a second phase of a clock is not required.
