Switching transistor Q4 is operated directly by the iW1690. Switch current is sensed across resistor R35. The
switching frequency of the iW1690 is approximately 75 kHz. The basic cycle-by-cycle operation of the power
converter is described briefly in the following paragraph.
With Q4 switched ON, current is pulled from the line through the primary winding of T2. Diodes D8 and D9 ensure
that the secondary windings of T2 do not conduct current during the switch ON time and energy is stored in the
magnetic field of T2. With Q4 switched OFF, the voltage polarity across the primary and secondary windings of T2 is
reversed, causing D8 and D9 to be forward biased. Current now flows in the secondary windings, delivering energy to
the loads. Bulk filter capacitance is provided on the main secondary output by C32. The auxiliary secondary output is
filtered at C35 to power the controller. The auxiliary secondary voltage is monitored by the converter at its Vsense
pin. This voltage is used to implement output secondary voltage regulation by setting the switch duty cycle.
The voltage on each of the rectified secondary outputs is determined by the primary voltage, the turns ratio of the
transformer, and the switch duty cycle, as follows:
