Functional Description
The IMX 4 DC-DC modules are feedback controlled flyback
converters using current mode PWM (Pulse Width Modula-
tion).
The converter 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 (
Io nom for the single and
Io1 nom + Io2 nom for the dual output types).
The close magnetic coupling provided by the planar con-
struction ensures very good regulation and allows for flex-
ible load distribution on dual output types.
