Title: METHODS AND CIRCUITRY FOR OPERATING SWITCHING POWER SUPPLIES
Abstract:
In described examples of controllers and methods for controlling power supplies, a controller (310) includes comparison circuitry (102) operable to compare a switching frequency of the controller (310) to a predetermined switching frequency. Voltage measuring circuitry (324) is operable to measure an output voltage of a power supply (300). Circuitry (352) is operable to disable at least one component in the power supply (300) in response to the switching frequency being less than the predetermined switching frequency and the output voltage being greater than a predetermined output voltage.
