Functional Description
The IMS 7 DC-DC modules are feedback controlled flyback
converters using current mode PWM (Pulse Width Modula-
tion).
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 shutdown.
