Functional Description
The IMX 35 family of DC-DC converters consists of two
feedback controlled interleaved switching flyback power
trains using current mode PWM (pulse width modulation).
Functionally the converters are of three main types. The
double output types consist of two electrically isolated out-
puts Vo1, Vo2. Vo1 and Vo2 derive from two power trains
and are electrically isolated. Voltage regulation for each
output is achieved with passive transformer feedback from
the main transformer of each power train. Adjustment of the
outputs voltages in the range of 80...105% of
Uo nom is pos-
sible by use of the Trim input on the primary side (See:
Block diagram, dual output types.)
The triple output types consist of 3 outputs Vo1, Vo2 and
Vo3. Vo1 (3.3 or 5.1 V) is generated by a power train using
state of the art Schottky diode (20 IMX 35) or a synchro-
nous rectifier technology (40 IMX 35) thus enabling high ef-
ficiency. Also there is active magnetic feedback on this out-
put via a pulse transformer which results in very tight and
reliable regulation of the output voltage. The other two out-
puts Vo2 and Vo3 are electrically isolated double outputs.
Vo2, Vo3 are restricted to being of the same output voltage
(i.e. D05, D12, etc.). Voltage regulation is achieved with a
passive transformer feedback from the main transformer of
that power train. Adjustment of the output 1 (
Uo1) is pro-
vided by the Trim1 pin referenced to the secondary side
and allows for programming of the voltage of output 1 in the
range of approx. 80...105% of
Uo nom. (See: Block diagram,
triple output types)
The quad output type consists of 4 outputs and two power
trains. Vo1, Vo4 derive from the first power train and Vo2,
Vo3 from the second one (thus each pair of outputs is inde-
pendent from the other one). Voltage regulation for each
pair of outputs is achieved with passive transformer feed-
back from the main transformer of each power train. Each
pair of outputs are restricted to being of the same output
voltage type (i.e. D05, D12, etc.). If both power trains have
the same output voltage, all outputs may be adjusted by
means of the Trim input. (In case of different output volt-
ages, the Trim1/4 input influences only Vo1 and Vo4. See:
Block diagram, quad output types.)
Current limitation is provided by the primary circuit for each
power train and limits the possible output power for each
pair of outputs. In the case of an overload on either of the
power trains which causes the output voltage to drop below
typically 60% of
Uo nom, the entire converter will shut down
and automatically restart in short intervals.
Overtemperature protection is provided for each power
train which will shut down the converter in excessive over-
load conditions with automatic restart approximately in
short intervals.
