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
dual output types consist of two electrically isolated outputs
Vo1, Vo2. Vo1 and Vo2 derives 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 via Trim input on the primary side (See:
Block dia-
gram, dual output types.) The triple output types consist of
3 outputs Vo1, Vo2, Vo3. Vo1 (3.3 or 5.1 V) is generated by
a power train using synchronous rectifier technology thus
enabling high efficiency. Also there is active magnetic feed-
back on this output via a pulse transformer which results in
very tight and reliable regulation of the output voltage. The
other two outputs Vo2 and Vo3 are electrically isolated dou-
ble 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 provided by the Trim1
pin referenced to the secondary side and allows for pro-
gramming of the voltage of output 1 in the range of approx.
80...105% of
Uo nom. (See: Block diagram, triple output
types)
The quadruple 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
independent from the other one). Voltage regulation for
each pair of outputs is achieved with passive transformer
feedback from the main transformer of each power train.
Each pair of outputs are restricted to being of the same out-
put 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 input influences only Vo1 and Vo4. See:
Block diagram, quadruple 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 fall less
than 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.
