V ext [V]
As a standard feature, the IMX35 offer adjustable output
voltages in the range of 85 to 105% of V o nom . Fig. 12 shows the
schematic diagram for the adjustment of quad-output models.
All models with equal output voltages have a Trim input at pin
5 referenced to the primary side, influencing all outputs simul-
taneously. Models with different output voltages exhibit a
Trim1 input, influencing only the first power train ( V o1 and V o4 ).

This logic input W can be used to synchronize the oscillator to
an external frequency source. This signal is edge-triggered
with TTL thresholds and requires a source frequency of 490 to
540 kHz (duty cycle 10 to 90%). The external source frequency
is internally divided by 2 to define the switching frequency of
the converter. If unused, this pin can be connected to V1– (pin
2) or left open-circuit.

Output voltage control by means of the Trim input
Adjustment of the output voltage by means of an external
resistor R ext is possible within the range of 100 to 105% of
V o nom . R ext should be connected between Trim (pin 5) and Vi–
(pin 2). The following table indicates suitable resistor values for
typical output voltages under nominal conditions ( V i nom , I o =
0.5 I o nom ).
Note: Connection of R ext to Vi+ may damage the converter.

Reference Output (Ref)
The converter provides a stable 5 V (±0.1 V) reference signal
on pin 7 (Ref). The output is protected by a 1 k ? resistor. The
signal may be used also in conjunction with the Trim input (pin
5) as a limited external voltage reference.
It is recommended to connect a filter capacitor (0 .1 μF)
between Ref and Vi–, if Ref is used.
Shutdown
The outputs of the converters may be enabled or disabled by
means of a logic signal (TTL, CMOS, etc.) applied to shut-
down (pin 8). If the shutdown function is not required, pin 8

For external output voltage adjustment in the range 85 to
105% of V o nom a voltage source V ext (0 to 20 V) is required,
connected to Trim or Trim1 (pin 5) and Vi–. The table below
indicates typical values V o versus V ext . Applying a control
voltage of 15 to 20 V will set the converter into the hiccup
mode. Direct paralleling of the Trim pins of converters of the
same type connected in parallel is feasible.
