Functional Description

Vi+

n.c.

Vo+

Vo–

The IMX4 Series converters are feedback-controlled flyback

converters using current mode PWM (Pulse Width

Modulation). The input is protected against transients by

means of a suppressor diode.

PWM

The output voltage is monitored by a separate transformer

winding close to the secondary windings and fed back to the

control circuit.

Vi–

Current limitation is provided by the primary circuit, thus

limiting the total output current (I_{o nom}for single- and the sum

I_{o1 nom}+ I_{o2 nom}for dual-output models).

Fig. 3

The close magnetic coupling provided by the planar

construction ensures very good regulation and allows for

flexible load distribution on dual-output models.
