IMS 15 Series

Functional Description
The IMS 15 series of DC-DC converters are magnetic feed-
back controlled flyback converters using current mode
PWM (Pulse Width Modulation). The -05- and -0503- output
voltage versions feature an active magnetic feedback loop
via a pulse transformer which results in very tight regulation
of the output voltage (see fig.:
Block diagram, single and
-0503- output types). The output voltages of these versions
can be adjusted via the R input. The R input is referenced to
the secondary side and allows for programming of the out-
put voltages in the range of approximately 80 to 105% of
Uo nom using either an external resistor or an external volt-
age source.
The voltage regulation on the dual and double output ver-
sions is achieved with a passive transformer feedback from
the main transformer (see fig.:
Block diagram, for double
output types). The output voltages can be adjusted via the
Trim input. The Trim input is referenced to the primary side
of the converter and allows for programming of the output
voltages in the range 100 to 105% of
Uo nom by an external
resistor or within 75 to 105% using an external voltage
source.The load regulation output characteristic allows for
paralleling of one or several double output units of equal
output voltages.
Current limitation is provided by the primary circuit, thus
limiting the total output power of double output types to
approx. 130% of
Po nom (see: Type Survey). The shut down
input allows remote converter on/off.
Overtemperature protection will shut down the unit in ex-
cessive overload conditions with automatic restart approxi-
mately every 50 to 60 ms.
