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 14):
The method of  claim 12 , wherein the transformer further comprises an auxiliary winding that is coupled to generate an auxiliary power voltage that is coupled to set an amplitude of the operational voltage associated with the control transistor device, the method further comprising regulating the amplitude of the operational voltage via a low dropout (LDO) power supply to clamp the control voltage at a predetermined clamping threshold in response to the switching voltage having an amplitude that is greater than the predetermined clamping threshold.
