Switching power supply control
A switching power supply controller includes a comparator to compare a feedback signal to a first limit and a second limit, one of which includes a ramp. Limit generators may be used to generate limit signals in response to power supply signals, control signals, and/or output signals. An error ampli...

| Zusammenfassung: | A switching power supply controller includes a comparator to compare a feedback signal to a first limit and a second limit, one of which includes a ramp. Limit generators may be used to generate limit signals in response to power supply signals, control signals, and/or output signals. An error amplifier may be used to generate the feedback signal in response to an output signal and an input control signal. A switching power supply may alternatively include an oscillator that shifts the switching frequency in response to the input control signal. |
