In one embodiment, a power supply system is configured to use a linear regulator to receive a first output voltage and form a regulated voltage during a standby mode and to use the regulated voltage to form another output voltage.

Power supply control method and structure therefor

In one embodiment, a power supply controller is configured to receive a sense signal (CS) having a negative value that is proportional to the input voltage. The power supply controller uses the sense signal to limit the switch () current through the switch responsively to the value of the input voltage.

Method of forming a switching regulator and structure therefor

An over-power compensation circuit for use in a switched mode power supply having a current sense circuit for sensing a current flowing through a power transistor of the switched mode power supply. The over-power compensation circuit includes a peak detector, a sample-and-hold circuit, a current offset generator, and an offset resistor. The peak detector has an input for receiving an input voltage derived from the input line, and an output. The sample-and-hold circuit has an input connected to the output of the peak detector, and an output. The current offset generator has an input connected to the output of the sample-and-hold circuit, and an output for providing an offset current. The offset resistor has a first terminal connected to the output of the current offset generator, and a second terminal adapted to be connected to a current conducting electrode of the power transistor.
