Patent ID: 8154264

Claim:
A switching converter comprising: a high side (HS) switch for coupling a node to an input voltage; a low side (LS) switch for coupling the node to a ground reference voltage, the LS switch operating as a synchronous rectifier; a circuit comprising at least two reactive components, one of the at least two reactive components being an inductor; the circuit being configured to provide an output voltage and switchable between at least two voltage states; an input of the circuit being connected to the node; a pulse controller configured to provide, to the HS switch, a control signal for controlling the HS switch, and to provide, to the LS switch, another control signal for controlling the LS switch; a feedback compensator component receiving a signal indicative of the output voltage from the circuit and providing feedback compensation signals to the pulse controller; a comparator component receiving a signal indicative of node voltage at the node, the comparator component generating an indicator of low load conditions; a threshold comparator component receiving the signal indicative of the output voltage, the threshold comparator component generating another indicator, the another indicator being indicative of whether the signal indicative of the output voltage is within a predetermined range; and a conduction mode control component receiving the indicator of low load conditions and the another indicator, the conduction mode control component providing compensator parameters to the feedback compensator component and providing a command signal for turning off the another control signal for controlling the LS switch, the command signal being provided to a logic component, the logic component also receiving the control signal for controlling the LS switch, and the logic component providing a resulting control signal to the LS switch.
