SPECIFICATIONS
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.
Designed to meet ultra fast transient
requirements: 300 A/s step load transients
15 A Current rating
Input voltage range: 10.8 Vdc to 13.2 Vdc
Output voltage range: 1.0 Vdc to 1.8 Vdc
Extremely low internal power dissipation
Minimal thermal design concerns
Ideal solution where board space is at a premium
or tighter card pitch is required
Industry standard surface-mount footprint
Available RoHS compliant

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 F 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.
