In a typical application, the NCX10S series
of DC/DC converters require nothing more
than a dc supply of correct polarity and
voltage to generate its specified output. These
notes are intended to offer help in the use of
other facilities offered by these converters,
and to provide assistance in achieving their
full potential.
VOLTAGE TRIMMING
The trimming (adjust) input on the secondary
side allows output voltage adjustment within
the capability of the power circuit.

Figure 1: Voltage Trimming
When open circuit, the trimming pin ADJ
operates at near half the output voltage. A
basic trimming arrangement consists of a
potentiometer of 10k
to 100k
connected
across the output, with its wiper connected to
the ADJ pin (see figure 1). Dependent on
model, the output will be reduced by about
15% when the wiper is at the positive output,
or increased by about 24% when at the
negative rail. Regulation will be maintained to
at least 10% adjustment either way.
If finer adjustment is required, a resistor may
be included between the wiper and the pin.
For example, 62k
will restrict a 3.3V model
to ±5% adjustment range. The corresponding
values for the 5V model is 56k
.
