  • Patent number: 10483856
    Abstract: System controller and method for regulating a power converter. For example, the system controller includes a first controller terminal and a second controller terminal. The system controller is configured to receive, at the first controller terminal, an input signal, generate a drive signal based at least in part on the input signal, and output, at the second controller terminal, the drive signal to a switch to affect a current associated with a secondary winding of the power converter. The system controller is further configured to detect a first duration of a demagnetization period associated with the secondary winding based at least in part on the input signal, determine a second duration of a time period for the drive signal based at least in part on the first duration, and keep the drive signal at a first logic level during the entire time period.

  • Publication number: 20190327812
    Abstract: Systems and methods are provided for regulating one or more currents. An example system controller includes: a thermal detector configured to detect a temperature associated with the system controller and generate a thermal detection signal based at least in part on the detected temperature; and a modulation-and-driver component configured to receive the thermal detection signal and generate a drive signal based at least in part on the thermal detection signal to close or open a switch to affect a drive current associated with one or more light emitting diodes. The modulation-and-driver component is further configured to, in response to the detected temperature increasing from a first temperature threshold but remaining smaller than a second temperature threshold, generate the drive signal to keep the drive current at a first current magnitude, the second temperature threshold being higher than the first temperature threshold.
