  • Patent number: 11677318
    Abstract: A circuit for controlling a switching power supply includes a disable signal generator generating a disable signal in response to an input clock signal, a timer circuit generating a timeout signal in response to the disable signal, a comparison signal generator generating a comparison signal in response to an output signal of the power supply, a first threshold signal generator generating a first threshold signal in response to the comparison signal, the first threshold signal having a value greater than that of the comparison signal, and a first comparator comparing the first threshold signal and a sense signal to de-assert the modulation signal when the sense signal is equal to or greater than the first threshold signal and the timeout signal has a first logic value.

  • Patent number: 10924009
    Abstract: A method includes converting an input signal into an output signal in response to a modulation signal, generating a timeout signal in response to the modulation signal, generating a comparison signal according to the output signal, determining whether the comparison signal is equal to or greater than a sense signal, determining whether the timeout signal has a first logic value, and causing the modulation signal to have the first logic value when the comparison signal is equal to or greater than the sense signal and the timeout signal has the first logic value. A switching power supply circuit includes a power converter, a timer circuit generating the timeout signal, and a controller causing the modulation signal to have the first logic value when the comparison signal is equal to or greater than the sense signal and the timeout signal has the first logic value.

  • Patent number: 9071134
    Abstract: At least one exemplary embodiment is directed to a method of switching between synchronous and nonsynchronous ramp control. An embodiment may include a power supply controller that has a trigger circuit configured to generate an RPM trigger, a timer circuit configured to generate a clock signal, and a switching circuit configured to switch a modulation mode responsively to the clock signal and the RPM signal.
