ABSTRACT:
An integrated circuit achieves a burst mode standby operation for a switched-mode power supply by driving a switching transistor. One winding of a transformer is connected to inputs of two differently biased rectifier circuits and the sum of the output voltages of these circuits is applied to a control terminal of the integrated circuit.
