摘要： A controller for use in a power supply includes a drive signal generator, a jitter signal generator, a compensator signal generator, and an arithmetic operator. The drive signal generator is coupled to output a drive signal in response to an input signal. The jitter signal generator is coupled to provide a jitter signal that is representative of a first percentage amount to modulate a switching period of the drive signal. The compensator signal generator is coupled to provide a compensator signal responsive to the jitter signal, where the compensator signal is representative of a second percentage amount to change a duty ratio of the drive signal. The arithmetic operator adjusts the input signal of the controller in response to the compensator signal to provide a compensated input signal, where the duty ratio of the drive signal is adjusted by the second percentage amount in response to the compensated input signal.

摘要： A controller includes a control, a sensor, and a fault detector. The control is configured to control a switch to regulate an output of the power converter. The sensor receives a signal from a terminal of the controller that is representative of an input voltage during an ON state of the switch and is representative of an output voltage during an OFF state of the switch. The sensor is configured to sample the signal from the terminal during the ON state to generate a first sample signal and to sample the signal from the terminal during the OFF state to generate a second sample signal. The fault detector detects a fault condition in response to either the first or the second sample signals. The control inhibits the switching of the switch to reduce a power output level of the power converter in response to the fault condition.

摘要： A current sense and feedback circuit is provided for a non-isolated Buck power converter to maintain constant current load regulation. The Buck converter may have a high side power switch and may include an input port, a switcher unit including a switch and a controller, an inductor coupled to the output, and a freewheeling diode for circulating the inductor current when the switch is open. The simplified current sense and feedback circuit of the power converter may include a current sense resistor module coupled to the freewheeling diode to provide a sense signal to the controller. The controller may also be coupled to the output of the power converter to sense an over voltage condition. The simplified current sense and feedback circuit may provide output regulation while maintaining a low component count, small size, and low loss that makes the power converter suitable for use in compact design applications.

摘要： An integrated circuit includes a high voltage transistor having a first terminal coupled to sense a high voltage terminal and a control terminal coupled to a regulated voltage, which is regulated with respect to a ground terminal and is substantially less than a high voltage that the high voltage terminal is adapted to withstand. A logic gate is also included and is coupled to be powered from the regulated voltage. The logic gate has an input threshold that is less than the regulated voltage. An input terminal of the logic gate is coupled to a second terminal of the high voltage transistor. An output of the logic gate is coupled to indicate that a voltage sensed between the high voltage terminal and the ground terminal is less than the input threshold voltage of the logic gate.

摘要： A controller for use in a power converter includes a sensor coupled to receive a signal from a single terminal of the controller. The signal from the single terminal represents an output voltage of the power converter during at least a portion of an off time of a power switch and a line input voltage during a portion of an on time of the power switch. A switching control is to be coupled to switch the power switch to regulate the output of the power converter in response to the sensor. A power limiter is coupled to the sensor to output a power limit signal to the switching control in response to the line input voltage of the power converter. The switching control is further coupled to switch the power switch to regulate the output of the power converter in response to the power limit signal.
