CONTROL METHODS AND CIRCUITS FOR ELECTRONIC DEVICES

This abstract first appeared for US patent application 18828103 titled 'CONTROL METHODS AND CIRCUITS FOR ELECTRONIC DEVICES

Original Abstract Submitted

A control circuit provides a drive signal to an electronic switch of an electronic converter. A first driving circuit has a first enable node receiving a first enable signal and a PWM signal generator circuit configured to provide a PWM drive signal in response to the first enable signal. A second driving circuit has a second enable node configured to receive a second enable signal and a PFM signal generator circuit configured to provide a PFM drive signal in response to the second enable signal. Logic circuitry coupled to the first and second driving circuits is configured to assert at least one of the first and second enable signals in response to a mode selection signal.
