Functional Description
The IMX4 Series converters are feedback-controlled flyback
converters
Modulation). The input is protected against transients by
means of a suppressor diode.
The output voltage is monitored by a separate transformer
winding close to the secondary windings and fed back to the
control circuit.
Current limitation is provided by the primary circuit, thus
limiting the total output current (I
I
The close magnetic coupling provided by the planar
construction ensures very good regulation and allows for
flexible load distribution on dual-output models.
