    摘要: Switching mode power supplies (SMPS) that can operate in a control mode for a normal load condition and operate with a burst-mode controller for a light load condition are disclosed herein. In one embodiment, a method for controlling the switching mode power supply includes when the load is in a light load condition, the switching mode power supply is controlled by a burst-mode controller.

    摘要: A switching regulator with fault protection and method thereof. The switching regulator comprises a switching circuit, a control circuit, a fault detection circuit and a fault timer. The fault detection circuit is electrically coupled to the switching circuit to detect whether a fault condition exists and generate a fault signal accordingly. The fault timer starts to time once the fault signal becomes valid, and is reset when the fault signal becomes invalid. If the fault time reaches a first time threshold, the control circuit is disabled, and the switch in the switching circuit is turned off.

    摘要: Switching mode power supplies and associated methods of control are disclosed herein. In one embodiment, a method for controlling a switching mode power supply (100) includes determining whether the switching mode power supply is in a burst mode. If the switching mode power supply is in the burst mode, the method includes recording a switching time with and without switching pulses to obtain a current value of an equivalent frequency and generating a peak current limit (V ir ) that decreases as a load becomes lighter based on the equivalent frequency (f eq ), thereby maintaining the equivalent frequency at the current value above an audible range. If the switching mode power supply is not in the burst mode, the method includes continuing to monitor whether the switching mode power supply is in the burst mode.

    摘要: A switching mode power supply with primary side control is disclosed. A signal containing input voltage information and a signal containing both input voltage information and output voltage information are provided to a subtracter to generate a feedback signal indicative of the output voltage. The feedback signal is then used to control the switching mode power supply to operate at desired mode.
