  • Patent number: 9572224
    Abstract: Thermally protected bleeder circuits for maintaining an input current of a power converter above a dimmer circuit holding current are disclosed. In one example, a bleeder control circuit may generate a bleeder control signal to control a bleeder current of the bleeder circuit based on an input current signal and a temperature signal. The bleeder control circuit may cause the bleeder current to be substantially equal to zero in response to the input current signal being greater than or equal to a reference signal, and may cause the bleeder current to be proportional to a difference between the input current signal and the reference signal in response to the input current signal being less than the reference signal. The reference signal may be constant for temperatures less than a threshold temperature, but may decrease with respect to increases in temperature for temperatures greater than the threshold temperature.

  • Patent number: 9401634
    Abstract: A controller for use in a power converter includes logic circuits to turn on and off a switch to regulate an output quantity. A first integrating capacitor is charged with a combination of a first current and a second current while the switch is turned on.

A reference generation circuit including a second integrating capacitor is charged with the first current during a previous switching cycle of the switch. The reference generation circuit generates a reference voltage in response to the second integrating capacitor. A comparator provides a stop signal to the logic circuits to turn off the switch in response to a comparison of a voltage across the first integrating capacitor with the reference voltage.
