The SMT12F series is a new range of ultra-compact non-isolated
point-of-load converters for space-critical applications. The new
SMT12F Typhoon™ family surface-mount converter has a footprint of just 13.5 x 16 mm - and unlike competitive products on
the market, requires only the addition of a small number of
ceramic output capacitors to realise a complete high-performance
point-of-load (POL) solution. The SMT12F is primarily intended for
use on very densely packed, high functionality boards and for
powering advanced silicon including network and communication
processors, DSPs, FPGAs and ASICs. A key advantage of the
SMT12F is that it only needs the addition of five 22 μF ceramic
output capacitors to provide a complete full-specification, high
efficiency POL solution with transient response capabilities that
extend up to 300 A/μs. The total board space required for the
module and capacitors is a mere 300 mm2, facilitating easy
co-location with the load.

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.

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.

Application Note 165 for further details.
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.
Ripple and Noise is worst case measurement. Typical value is 26 mV pk-pk.
When Vin <4.5 V, Vout max = 2.5 V for model SMT12F-03W2V6.
TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special
request, please contact your local sales representative for details.
NOTICE: Some models do not support all options. Please contact your local
Artesyn representative or use the on-line model number search tool at

Trim: A 1% 0.1 W resistor must be directly connected
between this pin and pin 8 (GND) to set the output
voltage to a lower value than 3.3 V. The temperature
stability of the resistor should be 100 ppm/°C or better.
The set point range for the 3.3 V model is from 3.3 V to
0.9 V. The resistor required for a given output voltage
