Abstract

See full text

In a control circuit for a switching stage of an electronic converter, a phase detector generates a drive signal in response to a phase difference between first and second clock signals. The first and second clock signals are generated by first and second current-controlled oscillators, respectively. An operational transconductance amplifier generates first and second control currents in response to a difference between a reference and a feedback of the electronic converter, with the first and second currents applied to control the first and second current-controlled oscillators. In response to a switching clock having a first state, a switching circuit applies first and second bias currents to the control inputs of the first and second current-controlled oscillators, respectively. Conversely, in response to the switching clock having a second state, the switching circuit applies the second and first bias currents to the control inputs of the first and second current-controlled oscillators, respectively.
