Board Mountable

DC-DC Converters

IMX 7 Series

Functional Description

In the case of the dual and double output units the output

voltage is monitored by a separate transformer winding

close to the secondary windings and fed back to the control

circuit. The R (Trim) input is referenced to the primary side

and allows programming of the output voltage in the range

100 to 105% of U_{o nom}by an external resistor or within 75 to

105% of U_{o nom}using an external voltage source.

The IMX 7 DC-DC modules are feedback controlled flyback

converters using current mode PWM (Pulse Width Modula-

tion). See block diagram for single and double output types.

In the case of the single output units the output is directly

monitored and fed back to the primary control circuit via a

pulse transformer, resulting in tight regulation of the output

voltage. The R input is referenced to the secondary side

and allows for programming of the output voltages in the

range 75 to 105% of U_{o nom}using either an external resistor

or an external voltage source.

Current limitation is provided by the primary circuit, thus

limiting the total output power.

The inhibit input allows remote converter on/off.
