The SMT15F-12 series are non-isolated dc-dc converters packaged
in a surface-mount footprint giving designers a cost effective
solution for conversion from a 12 V source. The SMT15F-12 has an
input range of 10.8 Vdc to 13.2 Vdc and offers an output voltage
range from 1.0 Vdc to 1.8 Vdc with a 15 A load, which allows for
maximum design flexibility and a pathway for future upgrades.
The SMT15F-12 is designed for applications that include
distributed power, workstations, optical network and wireless
applications. Implemented using state of the art surface-mount
technology and automated manufacturing techniques, the
SMT15F-12 offers compact size and efficiencies of up to 88%
at 1.8 Vout.

Notes
1 The SMT15F-12 features an ‘Active High’ Remote ON/OFF operation. If 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 SMT15F-12:
Configuration Converter Operation
Remote pin open circuit Unit is ON
Remote pin pulled low Unit is OFF
Remote pin pulled high Unit is ON
An ‘Active Low’ 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.
SMT15F-12S1V8RJ.
2 A 270 μF electrolytic input capacitor maybe required for test purposes only.
3 An external output capacitor is not required for basic operation. Adding
distributed capacitance at the load will improve the transient response.
4 TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special
request, please contact your local sales representative for details.
5 NOTICE: Some models do not support all options. Please contact your local
Artesyn representative or use the on-line model number search tool at
