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 19):
The circuit of  claim 16 , wherein the transformer further comprises an auxiliary winding that is coupled to generate an auxiliary power voltage in response to the primary current during a normal operating mode, the auxiliary winding coupled to set an amplitude of an operational voltage based on the auxiliary power voltage, wherein the circuit further comprises an auxiliary capacitor coupled to the auxiliary winding, wherein the control transistor device is coupled to charge the auxiliary capacitor during a startup mode of the power converter circuit to set an initial amplitude of the operational voltage.
