Functional Description
The IMX/IMY 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 as well as all double output versions fitted
with option R 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 output
types, -0503- types and double output types with option R).
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 output voltages in the
range of approximately 80 to 105% of
Uo nom using either an
external resistor or an external voltage source.
The voltage regulation on the dual and double output ver-
sions without option R is achieved with a passive trans-
former 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 program-
ming 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 charac-
teristic allows for paralleling of one or several double output
units with equal output voltages.
Current limitation is provided by the primary circuit, thus
limiting the total output power of double output types. 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.
