Output Voltage Adjustment of the SMT12F Series
The ultra-wide output voltage trim range offers major advantages to users who select the
SMT12F. It is no longer necessary to purchase a variety of modules in order to cover
different output voltages. The output voltage can be trimmed in a range of 0.9 Vdc to
2.6 Vdc or 0.9 Vdc to 3.3 Vdc. When the SMT12F-05W3V3J converter leaves the factory
the output has been adjusted to the default voltage of 3.3 V. When the SMT12F-03W2V6J
converter leaves the factory the output has been adjusted to the default voltage of 2.6 V.

Notes
1 The SMT12F features an ‘Active Low’ Remote ON/OFF operation. If you
are not using the Remote ON/OFF pin, leave the pin open (the converter
will be on). The Remote ON/OFF pin is referenced to ground.
The following conditions apply for the SMT12F:
Configuration
Remote pin open circuit
Remote pin pulled low
Remote pin pulled high
Converter Operation
Unit is ON
Unit is ON
Unit is OFF
An ‘Active High’ Remote ON/OFF version is also possible with this
converter. To order please place the suffix ‘R’ towards the end of the part
number, e.g. SMT12F-05W3V3RJ.
2 See Figures 1 and 2 for sample derating curves. For the full set of
derating curves see Application Note 165.
3 A 22 µF ceramic input capacitor may be required for test purposes only.
See Application Note 165 for further details.
4 An external output capacitor is required for basic operation. Required
capacitance is a minimum of 110 µF to meet the performance
parameters. This can be made up of any combination of 22 µF or 44 µF
multi-layer ceramic capacitors in the appropriate voltage rating.
5 Ripple and Noise is worst case measurement. Typical value is 26 mV pk-
pk.
6 When Vin <4.5 V, Vout max = 2.5 V for model SMT12F-03W2V6.
7 TSE RoHS 5/6 (non Pb-free) compliant versions may be available on
special request, please contact your local sales representative for details.
8 NOTICE: Some models do not support all options. Please contact your
local Artesyn representative or use the on-line model number search tool
