IMX4 Series Data Sheet

4 Watt DC-DC Converters

Functional Description

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.

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 single- and the sum

Io1 nom + Io2 nom for dual-output models).

The close magnetic coupling provided by the planar

construction ensures very good regulation and allows for

flexible load distribution on dual-output models.
