Functional Description
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
Uo nom using either an external resistor
or an external voltage source.
In the case of the 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-input is referenced to the primary side and allows pro-
gramming of the output voltage in the range 100 to 105 % of
Uo nom by an external resistor or within 75 to 105 % of Uo nom
using an external voltage source.
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 double output types).
The inhibit input allows remote converter shut down.
