CPC classification number: H02M3/1582 , H02M1/0009 , H02M1/0032
Abstract: A power conversion circuit includes a transconductance amplifier circuit, a current limiting circuit, and a controller. The transconductance amplifier circuit is configured to provide a first output current at a first output based on a differential between a first voltage at the first input and a second voltage at a second input. The current limiting circuit is configured to provide a second output current at the second output that is an input current at a third input limited to no greater than the first output current. The controller is configured to control first and second switches during a time period where the power conversion circuit transitions between an active mode and a skip mode.
