Abstract:
A flyback converter with adjustable frequency curve includes a primary winding configured to receive an input voltage, a secondary winding coupled to the primary winding to generate an output DC voltage, a feedback circuit configured to receive the output DC signal and generate a feedback signal, a multi-mode control circuit, an auxiliary winding configured to provide power for operating the multi-mode control circuit, an exterior adjustable circuit connected between the auxiliary winding and the multi-mode controller for adjusting the input voltage level of the input feedthrough of the multi-mode control circuit, wherein the multi-mode control circuit configured to generate a switch control signal based on the information associated with the adjusted input signal through the input feedthrough of the multi-mode control circuit and the feedback signal, and a switching device configured to receive the switch control signal and change a current flowing through the primary winding.

Claim (Index 11):
A flyback converter with adjustable frequency curve comprising:\n a primary winding configured to receive an input voltage; a secondary winding coupled to the primary winding and connected to a rectifier circuit to generate an output DC voltage; a feedback circuit coupled to output of the rectifier circuit of the secondary winding to generate a feedback signal; a multi-mode control circuit with a curve selection detecting circuit in its interior, wherein the curve selection detecting circuit includes:\n a comparator circuit having its input connected to an exterior adjustable circuit for detecting an input voltage and generating a control signal; and \n a frequency-reducing selection circuit connected to the output of the comparator circuit for performing a frequency-reducing curve selection based on the control signal outputting from the comparator circuit, wherein the frequency-reducing selection circuit includes: \n a decoder; \n a reference current source; \n a current adjusting selection circuit; and \n a curve adjusting circuit, wherein the reference current source flows into the current adjusting selection circuit and decide an adjustment current through receiving output signals from the comparator circuit by the decoder, the adjustment current instructs the current adjusting selection circuit to make a frequency-reducing curve selection; \n an auxiliary winding is configured to provide power for operating the multi-mode control circuit; an exterior adjustable circuit connected between the auxiliary winding and the curve selection detecting circuit of the multi-mode control circuit for adjusting an input voltage level of an input feedthrough of the multi-mode control circuit, wherein the multi-mode control circuit is configured to generate a switch control signal based on the information associated with the adjusted input signal through the input feedthrough of the multi-mode control circuit and the feedback signal; and a switching device connected to the primary winding and the multi-mode control circuit to receive the switch control signal and change a current flowing through the primary winding.
