R-Control for Output Voltage Adjustment
As a standard feature, single-output models offer an
adjustable output voltage identified by letter R in the type
designation.
Note:
With open R input, Vo = Vo nom.
The output voltage Vo can either be adjusted by an external
voltage (Vext) or by an external resistor (Rext1 or Rext2). The
adjustment range is approximative 0 – 110% of Vo nom. For
output voltages Vo > Vo nom, the minimum input voltage Vi min
specified in Electrical Input Data increases proportionally to
Vo/Vo nom.
Fig. 13
Output voltage adjustment
a) Adjustment by means of an external resistor Rext:
Depending upon the value of the required output voltage,
the resistor shall be connected:
either:
Between the R and G pin to achieve an output
voltage adjustment range of Vo
≈ 0 to 100% of Vo nom.
Vo
Rext1
≈ 4 k –––––––––
Vo nom – Vo
or:
Between the R pin and Vo+ to achieve an output
voltage range of Vo
≈ 100 to 110% of Vo nom.
(Vo – 2.5 V)
Rext2
≈ 4 k ––––––––––––––––––
2.5 V (Vo/Vo nom – 1)
Caution:
To prevent damage, Rext2 should never be less than
47 k
.
Note:
R inputs of n converters with paralleled outputs may be
paralleled too, but if only one external resistor is used, its
value should be Rext1/n or Rext2 /n respectively.
b) Adjustment by means of an external control voltage Vext
between G and R pin:
The control voltage range is 0 to 2.75 V and allows for
adjustment in the range of Vo
≈ 0 to 110% of Vo nom.
Vo 2.5 V
Vext
≈ ––––––––
Vo nom
Caution:
The external control voltage should be in the range
0 to +3 V to prevent the converter from damage.
