Abstract:
A power converter circuit includes a power stage comprising a transformer and a power switch. The power switch can be controlled in response to a PWM signal to provide a primary current through a primary winding of the transformer to induce a secondary current in a secondary winding of the transformer to generate an output voltage. The power stage includes a switching node having a switching voltage between the power switch and the primary winding. A switching controller includes a control transistor device to initiate an operational voltage associated with the control transistor device during a startup mode of the power converter circuit and to provide a control voltage based on an amplitude of the switching voltage during a normal operating mode. The switching controller generates the PWM signal in response to comparing the control voltage and a predetermined switching threshold voltage.

Claim (Index 2):
The circuit of  claim 1 , wherein the control voltage has an amplitude that is approximately equal to the switching voltage and that is clamped in response to the amplitude of the switching voltage being greater than a predetermined clamping threshold.
