摘要： There is described a circuit and a method of detecting a voltage polarity for the detection of a Continuous Conduction Mode to Discontinuous Conduction Mode boundary of a switched DC-DC converter. There is provided use of a dynamic current mirror to store in a first capacitor (C) a voltage representative of the conduction voltage (VDS(Φ1)) of the power switch, at the end of a conduction cycle of said power switch. Also, an auto-zero comparator is used to charge the output voltage of the dynamic current mirror into a second capacitor (C2), during the first phase of operation corresponding to a conduction cycle of the power switch, and to detect the polarity of the conduction voltage (VDS(t=TCLK)) of the power switch at the end of the first phase of operation of the DC-DC converter, by comparing the voltage stored in the second capacitor during the first phase of operation with the output voltage of the dynamic current mirror in a second phase of operation (Φ2) corresponding to a non-conduction cycle of the power switch.

摘要： Simple and efficient techniques for closed loop control of a boost converter. In an aspect, a current feed-forward (CFF) mode of operation includes providing current information to a control logic block controlling transistor switches of the boost converter to advantageously smooth the signals present in the closed loop control of the system. In another aspect, a modified peak current (MPC) mode of operation includes providing a simplified control mechanism based on a peak current mode of operation. Both CFF mode and MPC mode may share similar circuit elements, allowing a single implementation to selectively implement either of these modes of control. Further techniques are provided for determining average current information for the logic block.
