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 at
